That was a nice read o u o
I'm curious about Haru not being a real daughter, is there any chapter that explains this?
and also, I honestly felt some feelings from Yoko to Haru. I was expecting her to go "I know what it feels, because that's what i felt when I saw you being together!" when they were having some serious conversation in cubicle when the teacher officially announced that Kotomi is indeed leaving and switching schools.
