Hello guys!

I remember reading a story about a girl in love with a popular guy. I'm not quite sure that if they were friends or not. It's been a while since I read this so my memory is hazy. It might be a oneshot but I'm not sure. In this story, the girl is in love with this guy but this guy is kind of a player (or is one). The guy dates a lot and changes girlfriends often. Later, he starts dating this other girl and the girl gets jealous. I'm not sure about this but there might been another guy courting the girl. And stuff happen. Later on, the guy ends up having sex with the girl in an empty classroom or equipment room. And in the end, the guy reveals that he tied up and gagged the other girl and guy; he left them in the corner of the room hidden by desks? when he was having sex with the girl.

I've searched and searched for this manga but I wasn't having any luck. So thanks in advance.

Sounds like Shoujo, Smut genre.
I don't really like that type since most of it seems like NTR..
Did you try using the genre search? Try searching for just "smut". Might take a while but you should be able to find it if no one here can help.

Thank you for suggesting but I've done what you suggested above. I've tried searching smut and shoujo plus adding school life, drama, etc. Thanks though.

Lol, could it be one of the extras in the last volume of Men's Kou? I remember it because it was really random. Anyway, if it is, that's probably why you couldn't find it using genre tags.

It is Men's Kou. Thank you for helping me find it.
