However, she is an expressionless girl who doesn't talk much, and you can't read what’s on her mind. Still, she was extremely popular among the boys. In less than half a year since entering high school, the number of confessions she has received is said to be in the double digits. However, all of their confessions have been rejected by her. Thus, the nickname given to her is... The Cool-Headed, Peerless Angel Her nickname comes from the fact that she calmly analyzes her opponents, breaks down their arguments, and then rejects their confessions, as well as her angelic appearance. ‘Why is the cool-headed, peerless angel in front of my house? ’ "You're going to live in my house? "That's what I said.” "I'm going to ask you a simple question. Are you sure?" "What?" "You're going to live with a boy, who’s also a part of your class."

And you watch her change little by little, as the ice around her melts down. ~This is a story about such a situation.
