Title: Lack of Love
Hajin Park is trying his best to start his online fashion store, but it's a lot more complicated than he realized. His sister, a dentist with her own business, offers to help him out and set up his store online, but only if he does her a huge favor. She is a huge stan for the idol group 89, and while she has a ticket to one of their meet and greets, she's unable to attend due to work. So, she asks Hajin to go in her stead to get all of the member's autographs. While Hajin isn't looking forward to it, he agrees.
As Hajin is the only man there, he draws a lot of unwanted attention, including from the members of 89. To escape some of the crowds, he goes to the bathroom. While trying to find an open stall, he runs into Hangyum, the hottest member of 89, in quite a compromising position. After escaping the awkward encounter and the meet and greet, Hajin is all set to put all this idol business behind him when he is pulled aside by the manager of 89. The manager noticed how put together Hajin is and wants Hajin to become the personal stylist for the 89 members because their style is seriously bad.
Hajin is hesitant at first, but after discussing it with his roommate and sister about how it would eventually help his online business, Hajin calls back the manager's number. The manager is not who answers, though. Instead, Hangyum picks up and ends up personally striking a deal with Hajin. As a result, Hajin becomes Hangyum's stylist while also assisting the other members from time to time. But Hangyum doesn't intend on Hajin to just help him with styling. Hangyum and Hajin have a past, and Hangyum intends to heal the wounds they share.
