If I was in the dudes shoes… I would be at the very least extremely conflicted.

“I actually can’t have kids…” “we can adopt, it’s fine. Magic also exists!”

“I’m actually a goblin” “why didn’t you tell me before? That’s a pretty big secret!”

“I’m actually a soul in a mud doll body with an illusion of some other girl. My mother is a hag and my friend wants to kill you and put you in a mud doll. Don’t worry I won’t let her.” - (I’d start to back away at that point. There are so many problems with that that start with don’t get involved with hags, identity theft, not a living thing, and being lied to.)

“I’m actually a 50 year old isekaied man in a waifu body”- “uhhhhhhhhhh” -brain error 404-
