So basically, the uke and the pink-haired guy end up falling really hard for each other. Their love is actually real and respectful, not like with the black-haired ML where it was all admiration mixed with fear and obedience. They even elope together but the black-haired ML finds out where they are. At first he wants to kill the pink-haired guy but the uke says he’ll literally end himself if anything happens to the pink-haired ML. The black-haired ML is super torn, jealous, and frustrated but eventually he realizes this is the consequence of his own actions for not understanding the uke better and now it’s too late. He lets them be together so it kind of becomes a three-way relationship.

After reading the spoiler can't seem to read it further more. I usually like poly but not this way
