what's with those dirty mind, I just found this really cute, problem is the MC is a reincarnator so why he got so fidgety?! (or maybe the author or artist forgot that point)
It's pretty cute but he really is a bit childish for a reincarnated. Maybe this is like "By the grace of the gods" where the reincarnated's mind will retain a little bit of its childishness.
While the MC is a grown man I think the reason he’s acting childish might be like age regression from the abuse he suffered from his biological parents
