Was she about to punch him? I'm not sure what to interpret from the hand panels
Ye. She went really mad with the situation they're in.
They don't talk too much, and when finally they do, it's always bickering.
At one point, the husband brought out the divorce paper. The wife confronted it with Riri, the daughter, but all the husband said is just "I'm sorry", which shows his parenting commitment only ends up materialistic instead of also proper parent/mental support.
Reminder that, in the last chapter, we are shown how the "pillars" that support Riri is getting fewer. And now, it only gets even fewer.
