I think it’s the grandfather was their friend Bc it said the students grandfather owned the sweets shop and they had the same surname and in one of the memories of their past life the grandfather was in it because a boy mentioned they would treat someone to a sweet from his shop and that’s why the grandfather is so nostalgic but I’m not sure tho
yeah i also think that grandpa is one of the boy that both leads knows.... thats why its nostalgic. he didnt lose himself is probably becz he respect his wishes of the new him but he still wished to meet his past lover from that time and tell him something. the other one lost himself most likely becz his desire to be together forever even if he have to take over his other self.
Oooh I missed that part thenk u for explaining more
Thank*
No problem
Yes I agree, he was very desperate to be forever with the love of his life
I think one of them died in the past cuz the other one saved him and the other one is still alive and I think he is the grandfather of that student cuz he says that they have a piano at home and he learned to paly that song from his grandfather (in the first ch he said that his grandfather feels nostalgic reading the novel) and that's why the blond guy isn't loosing him self to the memories it's just a theory so it can be totally wrong which I think it is
