I'm looking for a yaoi manga...

although, I have almost no detail about it...

except for (one of) the story which I vaguely remember:

-the two character are students
-the seme is a bit sadistic or cruel to the uke when they are alone; but the seme acts nice to everyone else in school...
-they had sex, uhmmm, I only remember was that there was a cake involved, and near the end, the seme bit the uke's lip until it bled...

sorry for the info I could provide... I've been searching for it, but to no avail... I hope someone could help me... thank you in advance...

Happy Play ch3

wahhhhh... you're right... thank you so much...
hehehehe... I had so much difficulty looking for that one...
