do you have any physical characteristics of the charas? maybe it will kinda help
^ is it a manga or manhwa ??? HS or adults haha
can't remember characteristics. i think the uke was one of those tough to crack characters and well as one to hide that he is happy.
Manga. high school and I think it was with a teacher and student.
oh I think at some point the uke finds that he likes penguins.
So this manga is hard to find so I will break it down to the one thing I am almost certain of. it is a Yaoi/shounen-ai that begins with the uke helping another couple get together probably because of a bet or punishment game. only after that does his story start.
if this doesn't work then oh well. thanks anyway.
