Megumi is your son and Toji your husband. You and Megumi were arguing, it wasn't a serious one, It was just because the dogs had dirtied the house because Megumi didn't cleaned them

while arguing you said to Megumi that was all his fault and Megumi tired yelled to you

"Shut the hell up!!"

you didn't take It seriously but Megumi instantly fell silent looking intimidated at behind you. You chuckles knowing already. It's Toji, pissed off clearly about to beat your son up

"Try to repeat what you said, kid."
