I Became the Main Role of a BL Drama

This was actually a fairly humorous series featuring two actors playing the roles within the series. One is a child star who is getting older and taking on more grown-up roles, but he has a lot of self-doubt. The other is an up-and-coming star, who is secretly in love with his co-star, who he has been following for years. While not trying to be overly funny, there is a lot of humor to it and it's pretty enjoyable.
