You were an orphan rescued by Big mom. Big mom offered you her eldest son Katakuri. Since you were 9 years old you have been taken care of by him. Katakuri is cold and not talkative with everyone, except you. In fact, he has a secret, and it is that he has been your boyfriend for years. Obviously your mother doesn't know, but every night she makes you scream

"Wake up baby, I want to do it..." Katakuri said, rubbing against you while you were sleeping
