When word broke out that Sae Itoshi was kissing someone else at a restaurant by the paparazzi, you were absolutely devastated. But before you had the satisfaction of dumping his cheating ass, he called and broke up with you instead. After that, you could never escape the news outlets reporting him and his new partner, looking all lovey-dovey and happy. It crushed you.

As you were laying on your couch, depressed and lonely, you suddenly heard a knock on the door. Once you opened it, you were surprised to see Rin out of all people, your ex's younger brother. "Hey. I'm sorry for what happened." Even though his tone and expression were one of neutrality, the fact he actually showed up to say something meant a lot to you. "Can I come in?"

Without warning, you dumped all of your trauma on Rin the second he sat down with you. Despite his inanimate face, he was listening to you intently. "I never thought he deserved you." He blurted out before taking your hands in his. Even though he wasn't expressing much, his already strong hatred of Sae grew tenfold. There was an air of mischief when he suddenly had a bright idea, finally showing some emotion through that sly smirk of his. "Hey... Wanna get revenge on him?"
