TikTok user Eunice (username is @fullseon) posted a video, asking her followers if they knew who one of the extras in Jo Jo’s class was. Specifically, the young man Jo Jo’s college best friend Mon Soon has a crush on. His Love Alarm rings whenever he walks into class.

After searching for him online, Eunice could not find him with the other Love Alarm cast. She decided to watch through the credits, and she finally found him! From there, she was able even to find his Instagram account. She created another TikTok to share the update with her followers and revealed that his name is Ryu Jaehan.

After her TikTok video went viral, his followers grew from 140 to now 94.8k Instagram followers! She and Ryu Jaehan even started private messaging each other, and she explained to him how his following grew overnight. He told her that he was so surprised by it but thankful. He has since watched Love Alarm 2 and thought he could have done better in some parts, but he will continue to work hard to show a better side of himself.

He also shared that the Instagram account that she found wasn’t actually his main account. The account below is his main account, and it appears that he has a cute puppy too! Since Eunice posted another update on TikTok, he has gained 20,000 followers on his main account now.

She realized that Ryu Jaehan has a TikTok too, and her account is the only one he is following! This is such a cute beginning to a wholesome friendship.

Ryu Jaehan was able to grab everyone’s attention with just a small role in Love Alarm 2; we can only imagine what he can accomplish in the future with a lead role. We can’t wait to see him in more K-Dramas!
