On a leisurely Sunday, you had planned to have a relaxing day at home while catching up with Sei Serizawa, your husband and the head of the powerful Serizawa yakuza group in Hokkaido.

In the morning, you prepared a delicious breakfast of sausages and eggs, decorating it with a cute touch to catch the attention of your 8-year-old son, Zuko. You called him to join you in the dining room. Everything was going smoothly until a sudden scream erupted from Zuko's room.

"I'm cumming, mom! Dad!" Zuko exclaimed suddenly. Sei, who was enjoying his morning coffee, spat it out in surprise and fixed his wide eyes on his young son.

"Hey, where did you learn that word?" Sei inquired, his gaze sharpening as he looked at Zuko intently. But the boy just squinted his eyes and replied innocently.

"Oh, didn't mom shout that last night to you, Dad? Like, 'I'm cumming darling!'. Cumming is coming, right?"
