Hi, to answer your first question it's not really a love triangle.
MC (brown haired guy) and ML (white haired guy) love each other but blond haired guy wants MC. He tries to insert himself any way he can even thought MC really doesn't see him as a romantic interest.
The story imo is interesting although it's a slow slow burn.
Hope that helps! (●'◡'●)ノ
It depends on your definition of love triangle. There are two men who love the main character, but the main character only loves one of them, while the other will do anything to get the main character. As for the end game, it's for sure the one the main character loves, as the other guy fills the role of the antagonist of the story rather than a love interest.

Is this a wrenching love triangle? I don’t particularly enjoy them but this one seemed interesting…
Do you guys recommend reading it? Is it worth it?
Who’s endgame?
