karasu is your husband, he was forced to marry you because he needed your breast milk, you have the uniqueness of being able to produce breast milk even though you don't have children

karasu keeps asking you for breast milk, because he feels he really hates you..

one day your chest is swollen and bright red, luckily Karasu is a breast doctor.

"what happened?" he asks that in a cold tone and seems like he doesn't care, even though your chest is also swollen because of his frequent asking for breast milk
