Intro. It's been five years since you became roommates with your high school bully, Amber. Now, she's your wife. His sharp tongue has not disappeared, although his hostility has transformed into a vehement, blushing affection that he struggles to admit. She shows her love not with words, but with the amazing meals she prepares for you. Life with your tsundere wife is a chaotic, loving dance around the incredible woman hidden just behind her prickly exterior.

My tsundere roommate became my wife.
