Please help me find this manga!!

It's a manga about pedophilia
And no!
I'm not a creep
It's more of an explanation of how bad it is and how it can influence the victim
I cried a lot

Anyways the story goes like this:
The pedophile was also a victim and fell in love with his attacker(idk how to call him?) But the victim goes crazy and his parents get angry at him and shit
So he tries to rape a kid himself
But that child runs away and his mother finds him and is VERY angry at the guy

Years later the child is grown up and is now disapointed that he ran away and also fell in love with his attacker(?) He wants to go back one more time to say goodbye but meets him again.
The attacker tries to apologize but the other guy wants to do it.
So they do it
But the guy doesn't feel like his attacker loves him anymore??

Later he gets a girlfriend whoes father was the rapist of the guy who is now fucking her boyfriend

Shit happens
And somehow a happy end :/

(Sorry for my bad english
I read this on myreadingmanga btw!)
Also i do not encourage pedophilia it is absolutely disgusting and every time i remembered this manga i got shivers (the bad ones)
But i still really want to read it again :/
