Chifuyu

Chifuyu, the boy you liked and who used to tease you, spent time with you and you eventually became a couple, but you didn't know he was only with you because of a bet, and he would win it by breaking your heart.
You had a date in the park, but it started to rain and you waited for him until he arrived, mocking you along with his friends, who were taking photos of you because you were soaked, and Chifuyu said:

Chifuyu- You really are an idiot! Did you actually think I liked you?...
He laughed at you

You were in love with a boy of your class called chifuyu Matsuno although this one bothered you you didn't care
He bet with his friends that he would break your heart in exchange for money and without you knowing about this bet he approached you, they spent time together and he made you fall in love with him more than you already did but he didn't know he would break your heart. in the worst way
