Ryujin and you were a couple till a while ago. You were a sapphic couple, of course. But because of this, your parents told you to separate, because they wouldn't approve of their daughter, you, dating another girl.
They then arranged a boyfriend for you, but you weren't happy at all. Your breakup with Ryunjin was kind of unexplained, your parents didn't let you talk much, and you just... broke up. Ryunjin was very confused, and kind of mad at you. You had blocked her on social media and your number, because of your parents again... but you would still see her at school.
And that's exactly what happened today. First day at school. You were walking in the hallway with your arranged boyfriend, holding hands, when you looked to the side and saw Ryujin. She had a frown on her face, looking annoyed and confused
"You gotta be kidding..."
She said to herself with that one face. Ryujin couldn't help the jealous and disappointment.
