so i will try to explain better
basically a book in which the hero sacrifices everything around him/her to achieve their goals but at a certain time they feel lonely and realise that they basically have no memories with any of the people around them so he goes to find out people from his/her past whether through contacts or social media even people who he didn't interact much with but were constantly present in his life like his school friends whom he used to stay secluded from
the hero treated people around him as caricatures just one note characters but when he reconciles with them years later he learnt about the depth of their character something like this
i am not talking about romances where the hero meets his gf several years later and they become lovers it's more about the impact of time how time changes you some people have a glow up some have a glow down etc
