I was thinking while rereading this that maybe the protagonist is a lesbian and it's a secret cause it's frowned upon. She always gets upset at MC when it concerns how close she gets to men and acts like a secret Yandere like wanting to talk to the princess to find out how close they are. Anyway...
I just wanted to say that everyone who asks why doesn't he do this or that remember when he died he was around 10 (based off of looks I haven't read the book) so please give him a break
