Title: You Jin
You Jin isn’t the brightest bulb in the box, but even he finds it a bit weird when his female childhood friend Lee Sejin turns up on his doorstep, claiming to have contracted a potentially fatal disease with the convenient side effect of switching his gender. Sejin has been living his life as a man since the change but has run into some trouble with his gaggle of girlfriends. So he begs Jin to take him in until he can figure out what to do with his life moving forward. Of course, Jin is suspicious but lets Sejin stay with him all the same.
Once Sejin establishes himself in Jin’s life, he asks him for one more favor: help him grant his last wish. Naturally, Jin isn’t unwilling to help until Sejin tries to kiss him. As it turns out, Sejin’s last wish is a bit more than Jin realized. How far is Jin willing to go to help a childhood friend, if that even is who this person actually is?
