Firstly, who did not put the tragedy tag there???
Secondly, very controversial it might be, but I feel so bad for the grandpa.
Cowardice is a sin in such manners. And I actually didn't like how it just ended openly. I hate open endings, I hate tragedy.
Now for the controversial part, I feel bad for the gramps. Imagine seeing someone you loved so much coming back and saying "I loved you but I travelled and met your grandson and I fell for him because I didn't remember you. But I'm back to break up with you precisely because I time travelled and fell for your grandson."
Thay shit would hurt so fucking bad. I loved the story, but I hated the ending. I hated the grandpa's lover Troupe. My boy shiro lost his first love, kikujirou lost his love, kou who forgot his original love and fell for the one who resembled his love... The part where shiro goes "subconscious memories are really strong, eh" hit me so bad. Kou said he's a monster, but really he's just a tragic character.
But what really makes me dislike the amnesia Troupe, despite me consuming it like wild, is the love interest change. Esp like this. Kikujirou did nothing wrong, why does he need to see his love disappear and reappear just to tell him "I'm sorry, get married, love your fam" ???
Shit this hot too long, I'm over analysing because I have a weird habit of fixating on weird shit, if you don't agree with me, it's fine so please don't start an argument, but if you do, (rare) that's also fine. I just wanted to let it out.
