The manga i'm looking for is a shoujo manga about a cute looking boy in love with his older female friend. The beginning starts out with him as a child, trying to talk to the older girl he likes but is ultimately ignored by her. You know the kind of "aw, the cute little kid likes me" kind of ignore. Hes annoyed but takes it. Years later, after the two drift apart, the girl is going to a house for a tutoring job and meets a cute guy. She near swoons but gets to work.

Now here's where my memory fogs a bit. I might be wrong about what happens next.

Soon, as they study, the guy starts touching her and sex/rape happens. When she asks why later, he tells her because he loves her and she ignored his feelings before. After that, i think he black mails her to get her to keep coming back. I can't remember what happens after that.

Anyway, if anyone has any clue what manga this is, I'd appreciate it. Thanks.

Might be Aishite Kudasai, Sensei? I'm not really sure. It sounds similar.

I am vindicated!
I am selfish;
I am wrong!
I am right,
I swear I'm right.
Swear I knew it all along
And I am flawed!
But I am cleaning up so well
I am seeing in me now
The things you swore
You saw yourself...

No, that lady was his teacher. The girl im talking about is in her teens as well as the guy.

Jun'ai Koza Kemono Shiyou ?

close but no. The premise is about the same but the plot and art style are wrong. Although, it is a good read. thank you.
