I forgot what chapter but they mentioned in season 1 that wings are very intimate and normally only get touched by lovers during sex. Only ML is allowed to touch and groom Mc’s wing which is why he noticed he got horny from it.
I don’t remember which chapter either but I think celestials weren’t combative till Mc changed things and he never had to lift a finger to actually kill or injure anyone.

I have been reading this for a while but still wondering..
Why they focused on the wings in the smut scene so often? What does it means? And why touching the wings seems like such a big issue to them? Is it considered as their erotic/private part or something?
And.. why they keep saying something like “you are not pure anymore”. Is hurting others a taboo for celestial? That’s why they originally weak?
Can someone please explain ╥﹏╥
