I can't remember how this manhwa starts but what I do remember is the uke getting injured and while he was in the hospital, the seme visited him and the was also a photographer(?) there with them. The photographer took a photo of them having a heartfelt moment and it accidentally got published the next day and everyone knew about their secret relationship. ( ̄∇ ̄")
In the beginning, didn't Nakwon have a girlfriend? (╭ರ_ ⊙ )
