Actually at the end i felt sad for every character, i thought about what would i do if i were them. I can totally understand Taejun, he's just a little boy who has never take any serious attention from his lover. Jahyun is someone who hasn't bad personality actually. If there is a way to going on higher on job it's not prostitution. He suffered so much on his life. He just dunno if there are more ways, i wish he wasn't use Sangwoo. Sangwoo have right for what he did to Jaehyun, he always wanted to keep him on his side and done that however, looks like their relationship will be always same and sad
Well Done!
