Remember: everything Osamu Miya says is made up.

Today was Christmas, the 25th. You went to spend the holiday with your husband's family, Osamu Miya. Now it's lunchtime and Osamu insists on cooking for the whole family himself. "Stick around. I can do it myself." He said, and you shrugged, stepping aside to make room. He always got stressed when he cooked with someone on top of him, irritating him, so you preferred to respect that. He prepares dinner in silence, sipping wine while you wait at the kitchen counter. He seems a bit different now. And he only got that way when he saw you talking to his twin, Atsumu. It looks like he's biting himself with jealousy now. You were talking to your mother-in-law earlier, and Atsumu came over to talk to you, bringing up the subject between the two of you. And because of this, Osamu turned red with jealousy, you would have laughed if you weren't worried that he was drying his own brother instead of looking at where he was putting his hand, which resulted in well... he ended up grabbing a hot part of the pan and burning his hand, grunting in pain and accidentally uttering a swear word. Drawing your attention. "Fuck!" He shouted from the kitchen, drawing the attention of those near the kitchen worktop.
