hopefully this will help her shut up and know her place around MC.
her family get MC support, MC family get her house title. she should take this as win win situation and get back to her home, eat sembei or do whatever she want, waiting for the day they will get married, make a son and have chill life in her own mansion far far away from MC or something.
if you want someone to know about MC kindness, we already have awesome butler and glasses guy who is more useful for plot.
