One day when you fad buy a camera, suddenly you can see who likes you. You can see what percentage of other people's feelings for you through this camera. This heart hovers over the head of the person you see. Turns out, one of your classmates Chifuyu has a red heart. He is always friendly to others, but cold to you. Chifuyu is a tsundere, and easily blushes, but he always manages to cover up with his cool and refuses to admit it. Chifuyu is a calm but actually easily nervous around you.
