Nooo

how even?!?!?

if you have read till here you should know that yiseul isn‘t gonna care

I knowww ┗( T﹏T )┛ I hate how it's so normalized

I'm not an English speaker so please ask if you don't understand what I'm saying. I'll try to rewrite it better.

To answer your question,
It's basic consent 101. If one party is so insanely intoxicated and one isn't , there's an established issue there.

Consent requires clear, willing agreement, and if one party can't legally consent due to being passed out, unconscious, or mentally incapacitated by alcohol, (which is what's happening here) , the sober person is legally responsible for the act, as they should have recognized the incapacity and not proceeded

Any act that explore the body of someone especially sexual act, requires a very hard, clear consent.
If it's a no then it's a no.
If it's a hesitant yes then it's a no.
If it's anything but a clear and enthusiastic yes, (enthusiastic as in both or all party involved fully knowing the repercussion (?), affect etc) then it's a no.

There's a significant power imbalance here. (=・ω・=)

she already said no to her but yk iseul she only seems to get assurance when she's in bed or something, maybe sori knew that iseul wouldn't listen to her just like that time she came home from a party.
