He is drunk and so not in his normal state to make decision and they are not going out yet nor even kissed before so yes waiting for him to be fully conscious to initiate a kiss would be respecting him. "A kiss is not disrespectful" doesnt mean anything you need a context, you dont kiss people like that
"you must be fun at parties" isnt an argument and in any case i never go to parties because i dont like it so that's great :) you don't need a written consent but to be consenting yes. And in any case tis is a fiction so even if he does it, thats not something dramatic but i was really apprecing his concern for his teach (i dont remember the names i have bad memeory sorry) not drinking knowing how he reacts and taking care of him i find it cute and wholesome <3 that's all i was saying so i dont even know why you started arguing with me let's just appreciate the manhwa how about it?
Please don't kiss while he is drunk and not fully conscious i stanned you for respecting that my boy T-T i trust u , he is so respectful and loving to his teach thats so wholesome
