Yeah i know there's no such a thing as initiation rite but here's my better explanation of why came to my conclusion above, regardless of the absent of that rite, when he's about to come into a den full of dbags like that he should already have in mind what possible scenarios that would be happening to him so he could better prepared himself...
The fact is, in MC initial meeting when he proposed the idea of partner, he already COULD think as far as kissing will be asked from him....my thought then why not sex or why even not raping another kid?? (if you wanna have even more messed up possible scenario) when he already have other fact that they're a bunch of rapers... he all shock like that in front of the dbags when the negotiate the sex shouldn't happen at all.
If he's unable to think of some 'easy' scenarios like that in the beginning how the hell is he gonna do his revenge?? how the hell is he gonna save himself when the real shit goes down???? (And shit went down straight away & he couldn't even pull of the act...)

Its a bit spoiler but I can tell that he isnt seeking revenge by something extreme to the point killing them
The other guy will did it
And like the mc said in the earlier episode, what could happen between men?
From this statement we can conclude the mc just an innocent brat who didnt know BL Land was exist
And I could say he is a softie
Mc at first is like 'Imma get into this rapist club" but also like 'I have to have sex to get in?!!???!!' dude seriously...ofc something like THAT would happen I mean it's a secret club with a bunch of dbags why he even think that with as far as kissing will get him in baffled the hell out of me...sigh what a dumb MC... this is such a waste of a good revenge story :/
