Spoiler!
ml begins to feel the need for mc to have no "wants" and all he has to do is be yours, as that is no longer his option. after the fight between mc and ml (ml asks several times if everything he had done was in vain, trying to manipulate mc) Soon after that, a person appears (the mc is about to cry due to ml's manipulations) and so, the ml lets the mc go (as he had trapped him against the wall in a room when he had gone to get some papers for him). the teacher in a room) and so the chapter ends, with MC knowing that the ml is actually a BLACK flag
