This might be it (hope it is)
Welcome
It's not, but you guys have been giving me interesting mangas! I'll read this. Thank you so much.
It's not what I'm looking for but I appreciate the help. Thank you so much!
Hi! I only remember bits about this manga. Basically, the seme (straight) was interested to bottom so the uke kind of taught him (but the seme tops and the uke bottoms. Don't know how was that suppose to teach him anything haha). But anyway the seme fell in love with the uke during the process. I know it's quite vague but this is all I could remember :(
Thank you in advance. Btw, it's not a seke couple. The seme topped and the uke bottomed until the end of the story. Also, from what I remember, they are university students.
