Sis it is literally explicitly stated that MC is out of his mind and he’s ML's responsibility as he is his guide. Did you not read the story?
The guide even acknowledged the esper is in ENOUGH of his mind to be aware of the situation. We don't allow blackout drunkeness to be an excuse, so I sure as hell wouldn't excuse this hypocricy either. This isn't a one off with him, its habitual. He does it no matter his mental state, whether he's out of his mind or not. He does it deliberately
ML literally explains that MC is not in his right mind for most of the chapter, one time he says that to some level he can think because he's aware himself that he is not in his right mind and probably won’t remember any of it. When MC is in his right mind he keeps pushing ML away and when he isn’t, he goes crazy for ML because that’s literally a natural reaction for him, because of that in the past he was used by guides to do some perverted shit. Also literally in this chapter it is revealed that ML can easily call for help but he doesn’t want to. Didn’t you notice that up to this point ML keeps on forcing guiding on MC? He even showed up at his house. MC explicitly stated that he doesn’t want to have ML as a guide so he's trying extremely hard to find out what ML is up to
Also MC isn’t blackout drunk. You can’t really compare MC being out of his mind and extremely horny as a result of using his powers to just being drunk. You can kind of compare this situation to heat in omegaverse
So... in an effort to prove the other guy would rape him if given the chance... even though he said no so many times... he is now actually raping him in return? the guide already said no. this is sexual assault and its hypocritical, the esper is a piece of shit ngl.
