I think the father remarried? Because even before Yuki, Asumi said that Daiki was always alone, so i dont think that its a single parent house, maybe the dad is away for work? Because its not mentioned that Daikis mother is dead or something, if the dad dissapered, the real mother would have took him already... but again theres so much that we dont know yet... i just feel so bad for him!

Yeah the father remarried and Yuki was born. Daiki also became Yuki’s mother’s legal son that’s why he’s in her care now but I think the father left them that’s why Daiki feels indifferent towards her mother coz he keeps thinking that he’s not her biological son and you know teenage worries lol. But this is all my assumption I want know the whole story too huhu
You know what would be nice? That Daiki's parents started to act... like idk.. maybe it will sound stupid, but you know AS PARENTS?!
