Don't know what's realistic about a guy that's literally intruding someone's home and living in it, with the owner doing absolutely nothing about it but hey the manga is decent kinda.
I liked the story it’s actually quite cute and it’s slow-paced which I like.
However,
I don’t like that he was sleeping around with other women while he was still living with him and he didn’t tell him anything about him or his past and they just made up and confessed. It’s cute but uhhh made me feel a bit uneasy
