This story is meant to be read by adults who have an understanding that this behavior is toxic, but it's also a bit of a guilty pleasure for some people in fiction. I don't want to see people rationalizing it in the comments. Ya boy is a psycho top, and it's fun to read about. It's as simple as that.
I could imagine a plot point happening where the psychic guy continues to gain powers and eventually is able to alter reality or move to other universes (or whatever) and there being a whole thing where the psychic guy agrees with the mc that they are stuck in a bl world and asks him if he wants to leave or change things but the mc is conflicted because he has grown to love this world and ultimately decides to stay/not change things.
I like how you think
Maybe he already done that and forgot ,,
Maybe? (Though I am so happy that I'm not only one who was thinking of how slow this manga could turn into some sci-fi, LOFM, ORV, fantasy, mystery, eldritch horror thing.)
