@Bl lover😏💖 His practically ignored his family to live in the fantasies of bl novels anyway, miss his family, that's hilarious! The only thing he seems to mourn is his lack of Po**/Bl novels. Also exactly! He made the decision to stay in this world, to be mates with Nagi and share their lives and territory responsibilities. Yes the other two will die, but no where does it say instantaneous death, they will just have to die as nature intended, aging. So where is the excuse to cause his mate such emotional pain, when the other pair, aren't even an actual couple? For hundreds of years they just been doing nothing with all the perks of the job? Kotone is a bad mate for these reasons not because he didn't physically kill someone, but because his mates needs play second fiddle to a strangers want to live and never grow old and die.
I know it's fiction, but I still have an opinion and it can still pizz me off.
