Regret was something Satoru was well acquainted with, though, to everyone around him, he was nothing more than a heartless monster who cared for no one.
Truthfully, Satoru felt too deeply, his heart delicate like glass and easily shattered.
Only one person saw behind the mask Satoru wore, saw him as a human being and not a living weapon. Only one person had seen through the fake smiles, tearing down his walls to bring colour back into his bleak, lonely existence.
As he stares down at Nanami’s grave, Satoru regrets having never told him how he made his world brighter.
