There is only a couple of things that I remember about this manga. I know it was either a oneshot or only a few chapters long. It is about two friends who meet up at a high school reunion. They were best friends all throughout high school. The uke has a problem with remembering things. It seems that he forgot that his friend raped him at school right before graduation or something like that. Can someone help me? Thanks in advance ^.^

"Second Love" from Junjou to Furachi, maybe?

Edit: Linked here (as a manga tag within a spoiler tag kinda defeats the purpose of the latter)...

That's the one! ^.^ Thanks!
