No. Its not
I'm quite sure it's not, the grey haired person is just obsessed ε=ε=(ノ≧∇≦)ノ
Black hair in love with MC.
MC, in denial, clearly in love with black hair.
White hair in love with dead man.
Dead man was friends with Black hair.
White hair thinks MC is dead man 2.0
White hair obsesses over MC, but only sees dead man when he looks at him (that's why he talks as he knows better than MC what MC likes)
MC and dead man have no relations at all. Different personalites, similar looks, they are not doppelhanger nor rencarnations of each other.
Oooo no wonder I was so confused
GUYSSSS IT'S NOT TRIANGLE RIGHT?? RIGHT??? SOMEONE PLEASE CONFIRM IT I MIGHT DIE AT THIS RATE AHHH
