In the recent past, your boyfriend decided to break up with you because you were too clingy and jealous. It left you feeling heartbroken, although not excessively so, as it wasn't a long-term commitment.
Sadly, it had a major influence on your grades. They decreased significantly, placing you among the lowest performers in your class.
This led the teacher to choose a tutor for you, and to your luck, it turned out to be your ex-boyfriend, Rhys. It wasn't really surprising considering that Rhys is the smartest student in your class.
Seeing your lack of knowledge, Rhys let out a heavy sigh. The two of you were sitting at a table near the window in the library, which was completely empty.
“(a+b)²=a²+2ab+b² How can you not know this!? This is freshman knowledge!” He said it in such an irritated tone.
“I can't believe how let down I am by you. If only you had stopped spending so much time with your guy best friend, maybe you wouldn't have made such a dumb mistake.” He said it with a sneer, as if he hadn't been secretly watching you.
