Definitely the sharing part and the MC being aroused by it.
I'll be honest, hate me all you want, definitely a combo of the 1st and 3rd one. More 1st.
1st one feels obvious I mean just read my response lmao. 3rd one I never really thought about until you explained it like that.
It's a great VN, want to make that clear. Even if it's not my cup of tea I can still appreciate the effort the dev put into this and can appreciate good character writing and relationships. Also yeah based on the writing I overreacted definitely. Really made it clear those two are DEEPLY in love and nothing will break them which is one of the reasons I kept playing. I'm just not into the genres respectfully. Maybe I'll come back after Ive opened my mind a bit more to sharing and the MC being turned on by it.
Have fun guys. Good luck Dev and thanks again
