the MC isn't the driver behind the ML blackening. There is actually a wider plot going on that the MC didn't know about, and he is a side character to this bigger story.

the reveal about the ML's thinking was completely heartbreaking.

it's extremely debatable if the ML deserved such a happy ending, given how awful the things he did were. But the ML and MC's relationship was so cute, and their adopted daughters were so cute, I can't help but love it.

he bullied him because his shizun (MC) would always talk mad crap about ML being ugly and due to that he started to bully the ML. The MC didn’t do sh*t about it and let ML get bullied. ML was bullied for a lot of sh*t and almost even died at the process MC would know these even knows about ML almost dying due to it. On the current life hes a jealous little boy since his shizun seems to be paying attention to the guy who he hated a lot and even took him to the competition that MC never took ML to. He crashes it and cuts MLs mask through his power and MLs face is revealed to the public

separation arc starts ML comes back and the little villain feels sorry and seems to have some conscience of wanting to apologize but does not get a chance whatsoever. ML ignores him, gives him cold shoulders, says goodnight to MC and the girl (later adopted daughter), but not to the little villain. Brings 3 mask of foxs but not to him. While he sees ML, MC, and the girl his monologue hits with being left out since he can’t fit in with his deer mask and completely ignored.

dude had to find out that his whole family were killed. He went through all the corpses to find his family, he was bloodied mess trying to find his families bodies.

ML imprisoned him and did not care two crap about him other than abusing him. He left him alive because “shizun wants you to live.”

Gets thrown in a cage that’s with a wolf in front of everyone and even his shizun, who is powerless held by ML. His neck gets bitten by the wolf.

Tries to stab and does stab ML, but oh magical things happen and his shizun and ML reconcile and gets together

It is HE but the kind where I kind of wish it wasn't. I don't think the wrongs of the ML deserve forgiveness and acceptance from the MC.

Living happily ever after feels so disconnected from the manic and cruel revenge of the past and present lives.

This is a hurt and comfort story but the hurt is too much and the comfort is both inadequate and undeserved.

It also featured a plot I personally hate where the ML slept with a bunch of women to try get over the MC. So if you hate that too, be aware of it. It is really gross to me.
