Judging from the height difference, maybe the father got divorced with the Japanese mom with mom getting custody, moved to another country and got married having two kids
I think it's possible
This makes the most sense as well. And it's probably what the author intended of showing. I feel like the western perspective is to jump to cheating when it comes to this type of situation, and they ignore all other factors.
I like the concept it's Interresting, but I'm I the only one finding it weird that the two women live together like no problem, if my husband cheated and got 2 kids with another women like hell I would take care of them heute should do it himself and never contact me again
