My Boyfriend Always Thinks He's a Scumbag

This is still just a rough idea, not fully developed. To sum it up, a goofy top loses his memory and decides that his past self must have been a scumbag.

He suffers all kinds of anguish, convinced he isn't good enough for the bottom and wanting to break up with him.

"He's so wonderful. I don't deserve him, so I've decided to break up with him."

"Waaah, but breaking up is so hard. I'm in so much pain."

"No, I'm a scumbag. Scumbags don't deserve love."

"I'm such a scumbag. I'll scatter my own ashes to give him some satisfaction."

"But I can't bear to leave him, waaah."

Theme: Love means being devoted to only one person.
