Bruh the MC didn't just lose his memories he have multiple personality disorder at this point

Wtf was that dude? Recovering your memories back means losing the new memories you created and also losing your your personality? Wtf the author can just say the MC has a Multiple personality disorder. But nah the MC is just a piece of cunt who is very insecure of the ML since they are young. MC with his old memories pisses me off so much
