Boob window is designed to remind us that characters have boobs. Let’s don’t forget about male characters. But I don’t think he is thrilled.
I definitely appreciate how pronounced his man-boobs are in this drawing. So… It’s a
moob pec window! What a nice change of pace 🙂
Apparently the screencap is from a jRPG titled Atelier Iris 2: The Azoth of Destiny.
edit: Switched up “moob” for “pec”, as the former is considered a body shaming (and/or transphobic) term.
