i think it was honestly the best choice to kill seme ngl
like consider that towards the end, his killings became more impulse rather than driven by his childhood feelings and whatever else, so thats why uke had kind of become disillusioned with seme after realizing hes just like every other serial killer; 'garbage' as he calls it
which makes much more sense as to why he killed the seme in the end
weve already been told hes manipulative and does whatever for his own sake, hence the final act where he seemingly becomes nice to seme again only to kill him
knowing that by that point, he doesnt exactly feel as fond towards seme since hes become a regular serial killer and targeted one of ukrs only friends, i think it makes the most sense that he wouldve killed seme
additionally it was already hinted at that the therapist would die if you consider semes revisions of his novel where he kills off one lf the side characters in his novel for the main characters development, a reflection of what was to come in ukes own life which was 100% intentional
and the therapist had already accepted the danger that would come with pursuing a literal serial killer but did not choose to listen so i cant exactly feel bad (-_-")
Omg thank you so much. I think I get it. And the novel omy thats true. Seme did killed off some. And the doc was a part of it. Damn , so seme has already become a regular serial killer, and even uke could not stop him? Some thing like that? I wonder if there was a possibility of keeping seme alive and uke controlling him. And also the therapist lives. I did see his death coming but still I hoped he wouldn't really die.
Thats just what I thought. You explaind it clear which made sense. Thank you.

I dont think i got this properly. In the end everything feels like so simple or kind of disappointing. Im not sure. I mean so uke killed the killer, and the last chapter it says that was the best decision and uke was with the finger. I hope that seme didnt die like that well he had his own shit going on. And uke probably knew or understood him. And the therapist i ry feel sad. I dont think he should die. Why this... there could have been some other way to stop all. Of this. I thinm if uke had been thought more or if he could just been more considerate.. but yeab uke might not feel comfortable still .
I really loved the story it was so good interesting I like the characters.
