I don't think we know dad is dead, he's just not in the picture. Maybe he ran off, or he's totally useless, or mom got pregnant outside of a relationship.
Motivations: apart from the kiss at the end it all seemed quite natural to me. Touko is a slob doing an old friend a favor. Akari is nervous but Has Standards and is domestic, also finds Touko pretty/hot. Nothing requires explanation.
Kissing your friend's 16 yo daughter (2nd spring of Japanese 3-year high school) who's now trapped living with you, within 24 hours of meeting her, well. Best to apply the "porn plot" filter rather than the "psychological realism" filter, it seems.
Hmm, the previous version gave Touko the excuse of being drunk.
The pixelated kitchen and food are funny. How bad can it be that you don't want to show it?
