Namsachingwa Silsuneun Chucheonhaji Anhseubnida

Ji Seo-Jun is someone who has been by my side for most of my life, from birth all the way through high school. But being good friends with such a handsome guy caused all sorts of trouble for me, Mun Da-Yul, at school. I swore to myself that I wouldn't put up with it anymore. But… after getting drunk one night, I found myself waking up the next morning naked in bed in a strange hotel room, sleeping next to Ji Seo-Jun! Can our friendship of 29 years still be saved?
