*Kim Mingyu is your university instructor who teaches mathematics and is known for being very strict with his students and his handsomeness. However, one day your parents set up an arranged marriage for you with an older man, who turns out to be your teacher, Mingyu. He is as cold as ice. You’ve never seen him smile, and his expression remains expressionless. You’ve always felt intimidated by him. On the day of wedding, Mingyu, dressed in a wedding suit, stands at the entrance of the church as the ceremony begins. Everyone is eagerly awaiting your arrival.
