After finishing the recording of "Family is Coming", Yoon Hyun returned to Seoul and immediately started filming the MV for IU's title song.

  The background of the MV designed by Yoon Hyun is a young girl who inherited her grandfather's legacy as a craftsman in a family of craftsmen. In addition to various mysterious tools and products, there is also a sleeping man in the workshop. One day, IU accidentally started time traveling while riding on her grandfather's mini train, and through the train window, she saw images from the future, where she saw that the man lying in the workshop would be her boyfriend in the future. After learning this, IU began to take good care of the sleeping man and worked hard to develop a time machine. After a long effort, she finally succeeded in creating the machine when she grew up, and she could finally travel through time with it. Just as she was about to leave, the sleeping man woke up...

  When IU saw this script, she pouted and even wanted to refuse filming. This was completely different from the feeling of the song in her mind!

  "Take the picture, whether you want to or not. If you don't take it seriously and do a good job, I never want to see you again." Yoon Hyun pulled out his authority, suppressing the reluctance in his heart to force IU into submission.

  He had already been moved by IU's tears and was thinking of rewriting the script and re-shooting.

  But suddenly he remembered that Full Moon and Xian Jing were also preparing to debut, and it was estimated that the debut stage would be arranged soon. If they debuted at the same time as IU's comeback, wouldn't he be even more embarrassed?

  So, without being polite to IU and not treating her as an outsider, Yoon Hyun-ji made a decisive decision: to complete the production immediately and arrange for a comeback on stage.

  Poor IU was still thinking depressingly about why OPPA knew what kind of song he wanted to make but didn't do it that way, when she was already betrayed by the person she trusted most...

  All MVs were indoor scenes, and in the two days when Yoon Hyun went to film "Birth of a Family" while director Lee Yun-jeong was filming another MV, the studio had already been set up according to Yoon Hyun's script.

  The entire shoot was completed in just one and a half days.

  Yoon Hyun's last concession was to lie on that bed and play IU's future boyfriend.

  "Oppa, did you forget something?" After the MV shooting was finished, IU approached Yoon Hyun.

  "What's wrong?" Yoon Hyun was taken aback for a moment, thought about it, and felt like he hadn't forgotten anything.

  "This title track doesn't even have a name yet!" IU said with some annoyance.

  "The song was written by you! The name should be decided by you." Yoon Hyun suddenly realized.

  "It's still up to you, OPPA. The album is about to be printed and the title song hasn't been decided yet. Many people are waiting to see me make a fool of myself." IU said with a bit of frustration.

  "Let's just call it IU then. This song." Yoon Hyun said after some thought.

  "Isn't this a bit strange?" IU's face turned red and she looked a bit embarrassed.

  "That's good, then use a small heart shape as the background for 'and' in between, it should be quite cute." Yoon Hyun said.

  "Uh-huh." IU said thoughtfully, as if there was more to her words.

  "You've decided then." Yoon Hyun said foolishly.

  "Thank you, oppa!" IU bowed slightly in disappointment towards Yoon Hyun and then left.

  Then IU's comeback officially entered countdown.

  That night, IU's comeback news was announced on LOEN's official website, along with a 30-second making film and recording of the title song "You and I".

  The next day, the details of IU's self-titled album were released. The entire album consists of 6 tracks, all written and composed by Yoon Hyun-sang except for the title track "You & I", which he also produced himself.

  If the news released on the first day was a dying struggle that wouldn't attract anyone's attention, like a small girl who debuted last year and didn't even stir up a small wave, then the second day's news was like a 10-magnitude earthquake in the ocean, stirring up a tsunami of frenzy.

  Although Yoon Hyun has not appeared on stage as a singer for a long time, in the music world, Yoon Hyun has become a legend in just two years.

  "Yin Xian's products must be of high quality."

  This has become an acknowledged fact in the music world.

  Not to mention the songs sung by Yin Xian himself, which span multiple languages and successfully landed on the world's largest stage, just talking about the songs he wrote for others.

  "If" made a little girl from an unknown company's girl group the top choice for a TV drama OST. Although last year's Golden Disk, Kim Tae-yeon won with a different song, even now, whenever she appears on any program, "If" is always her must-sing song.

  While Girls' Generation, the girl group Tae-yeon was in, suffered the biggest blow to a Korean idol group with the Black Ocean incident, almost everyone lost hope for the group's future. However, just six months later, Yoon Hyun used his composition "Gee" to successfully put these nine girls back into the history of Korean music, achieving an unprecedented 9 consecutive wins, a feat that even the most popular TVXQ would have to look up to.

  Yoon Hyun was just a friend Park Myung-soo's wedding in a few minutes to write a wedding celebration song "Fool for Fool", then successfully helped serve one and a half years has faded out of people's sight Kim Jong-kook, back to the music scene shine.

  Such a person helped an unknown little girl write a whole album!

  What's even more eye-catching is that Yoon Hyun-sang, who has always insisted on not singing other people's songs, actually composed a song with lyrics written by IU and chose it as the title track!

  The entire music industry suddenly woke up from Girls' Generation's whirlwind and began to eagerly anticipate Yoon Jong Shin's production of this album.

  Unlike the outside world's expectations, Yoon Hyun's fan café was filled with mournful cries.

  "Will OPPA never go on the path of a producer from now on? I still want to hear OPPA sing!" Posts like this almost flooded the entire forum.

  Afterwards, Yoon Jong Shin arranged for LOEN to release the song on Melon and other music sources.

  The three songs released instantly occupied the top three positions on the download chart with a sweeping momentum.

  Those previous doubts about whether Yin Xian can do a good job as a producer also disappeared at this moment.

  Soon, over the weekend, Yoon Hyun-joon arranged IU's comeback stage on MBC TV's Music Core, which does not have a ranking competition.

  Nothing else, just MBC and I have a good relationship.

  "Oppa, my stomach hurts a bit." IU, who had visited all her senior singers under the guidance of manager Kim Soo-yeon, is now waiting in her own lounge for her juniors to visit, feeling a bit flustered and at a loss.

  "Are you so nervous when you first stepped onto the stage?" Yun Xian couldn't help but laugh and cry.

  "There wasn't... At that time, I thought OPPA would watch my performance, so I had to do well." IU said with a bit of embarrassment.

  "It's okay, I'll still be performing on stage later." Yin Xian said with a smile, "This song has a relatively high pitch, don't get too nervous, or your vocal cords won't open up..."

  Yoon Hyun-jung was joking with IU when his phone suddenly rang.

  "Oh, Jung-won-ah! What's going on?" It was Park Jung-won, the president of Yoon Hyun's fan club.

  "Yoon Hyun OPPA, isn't today your trainee IU's debut stage?"

  "Yes! I'm now accompanying her backstage waiting for our turn to go on stage."

  "We discussed it among ourselves and thought that OPPA's student might not have too many fans coming to support her at the scene, so we organized dozens of people to come."

  "You? Now you're here?"

  "We're already inside the venue! OPPA, don't worry, we didn't bring any cheering signs, just a few IU sister light sticks!" Park Jung-hyun and Yoon Hyun were close friends, so she naturally knew what he was worried about.

  "That's great!" Yin Xian put down his heart and said, "You guys have worked hard!"

  "It's okay! OPPA's student is our sister too! We support her as well! And, please tell IU sister that she sings really well! We all like it!"

  "The phone is on speaker, she can hear!" Yin Xian said with a smile.

  "Thank you, Jung Eun-ji sister! I'll work harder!" Hearing the encouragement from Yoon Hyun's fan, IU's heart also warmed up.

  "Go for it! We'll be cheering you on!" Park Jeong-hyun said finally before hanging up the phone.

  "How is it? Are you still nervous?" Yoon Hyun looked at IU with a smile.

  "It can't be. But I'm really envious that OPPA has such great fans! If they were my fans, I'd be happy to death." IU said with a face full of envy.

  "Then sing well. My fans are all good people, if you perform well enough, they will also support you and cheer for you!" Yoon Hyun encouraged.

  "Then isn't this digging under OPPA's wall?" IU burst out laughing.

  "What's the point of you and I being so clear about it?" Yoon Hyun also laughed.

  Because IU's comeback has Yoon Hyun's blessing, plus LOEN company's Melon has had a deeper and deeper influence on music programs, so LOEN artist IU's comeback stage was naturally placed in a very important position that doesn't match her fame at all.

  "Gazing at the clock's whispering secrets"

  The stories I yearn for most in my heart...

  As the music began, IU, dressed in a cute tight mini dress, started singing on stage.

  Yin Xian is now at the entrance of the passage under the stage, watching quietly.

  After her own intense training, IU's breath control has also improved a lot. Well, this high note is still slightly floating, but it's already very good. She's still dancing...

  Yoon Hyun looked like a teacher at this moment, seriously grading a student's test paper...

  On stage, IU, who had started performing, had already forgotten her nervousness, singing her song while trying to find Yoon Hyun in the audience below. The fans who came to support Yoon Hyun showed enough professionalism.

  However, IU couldn't find Yoon Hyun.

  But she knew that Yoon Hyun was definitely watching somewhere.

  So she worked hard at it.

  The music ended, and the whole audience erupted into warm applause.
