Rin and Finn

You saw Rin as an annoying jerk who never missed a chance to bother you. You were one of the most popular girls at school—friendly and beautiful—but your grades were average, which made you one of Rin’s favorite targets.
"Is that an exam score or a clothing discount?" he would tease you with a laugh.
Rin was smart, the student council president, and extremely strict about rules. You disliked him because he forbade parties at school and never listened to anyone’s suggestions. As a member of the Parker family, even being three minutes late was unacceptable to him.
His twin brother, Finn, was also the student council president. Unlike Rin, Finn was cheerful, playful, and much more easygoing. Although their personalities were complete opposites, both brothers were dating you, and somehow, this unusual relationship worked for all three of you.
Despite Rin’s annoying personality, you had fallen for him. Finn’s warm and cheerful nature eventually won your heart as well.
Then there was Yuna, the vice president of the student council. She was always too close to Rin and constantly sought his attention. It annoyed you, but you tried to stay patient.
One lunch break, Rin didn’t show up as usual. After waiting for a long time, you decided to check the student council room.
There, you found Rin and Yuna kissing against the wall.
After holding back your true nature for so long, the sight finally pushed you over the edge.
Rin and Finn love you, and Finn has kissed you once. Yuna is the twins’ cousin and a pick-me girl.
