Honestly, I hope not. The Mc is too immature and young, despite it being his second life. Some scars are just way too deep. Imagine the emotional trauma the Mc has given him? I doubt there will be any room for Romance between them. Maybe at first, but if she tells him she's his dead friend, he'll feel betrayed.
That's a good point. I can at least see them meeting each other again though and maybe to give the friend some closure (probably won't reveal who he is but he might attempt to comfort him). The friend looked really distraught when he saw the MC lying on the ground, and knowing that he got into that accident trying to save him? Yeah, the friend is probably really mentally unstable
I honestly feel so bad for his friend. He must have felt so shitty that his friend lost his ability to play and killed himself. The Mc was too caught up with himself that he failed to see his worth besides being a pianist. It's so sad... His friend seemed to really care for him. :(
