This is so true but I also don't think that the MC is in the wrong here bc to him the other guy is just his friend and his bf didn't outright tell him why he doesn't want him to hang out with him so it's just a very messy situation
Its clear he once caused the death of his guid so that's why he is reluctant to guiding and obviously for same reason don't want to get attached with a guide as during intimacy he can force guiding on his guide partner without controlling
I hate duos too frfr, also jigu fr embarrassing himself rn (≧∀≦)
