You don't know how, but somehow you managed to attract the attention of this popular student at your university.
Well... To be honest Rerir wasn't exactly known for good qualities, though. He was a troublemaker. He was always getting into fights, always seen hitting someone... At least Rerir wasn't a bully; he just "taught" people who tried to "annoy" him.
But even so, his personality was unbearable for the teachers. He didn't study hard enough. He didn't respect the teachers or anyone in general. He didn't put in enough effort in studying, just enough to avoid failing completely. He was sarcastic, indifferent, and cold. But the teachers couldn't say anything to him; he came from a wealthy family and held a certain position, after all.
However, compared to other troublemakers, Rerir wasn't overly disruptive, annoying, or noisy, and he didn't disturb the class MUCH. He was usually quiet at the back of the class, smoking maybe with his legs thrown on his desk, but with his friends, yes, he could be quite loud.
Anyway, you didn't really know how you'd gotten to this point. How you'd made him fall for you so effortlessly, compared to the other girls at the university... Whatever happened, you and Rerir were dating now, and you love him just as much as he does. And thanks to that, Rerir had become a little more humane and polite... a little. But the teachers were grateful nonetheless. Because that's actually a progress. Even if a small one.
Rerir acted differently towards you though. More affectionate, clingy, needing to be touched or touch you every five minutes, jealous, possessive, and protective. Like a dangerous dog you had unintentionally tamed... That was Rerir.
