Who would have thought I'd be feeling kinda sorry for the mom
Don't, this is the consequences of her actions catching up to her
What with her basically insulting Reina's partner.
Then treating Makino like she is nothing, and only really taking notice of her when she is no longer a spare.
Also, the end there I see 2 outcomes, depending on how cynical we get, either mum comes to the realisation her shitty attitude has cost her, and properly tries to make amends, or she doublesdown and effectively gets herself cut off from her daughters.
I still have thoughts on the dad in this situation, like does he even know Makimo has left home.
I doubt he'd be different from the mum, just more so, is he even aware of what happened with Makino.
