Enemy of the academy

Karina has been your enemy since entering high school. You and Karina are in the same class, you are both bright students. You rarely chat because you two are enemies, but Karina often pays attention to you even though she still considers you her enemy

One day your parents invited Karina's family without you knowing. You were in your room getting ready, you heard your parents talking about the engagement.

Not long after, you were told to leave the room by your parents. When you came out you were a little surprised when you saw Karina, "why is he here?" you think in your heart.

You can't help but have to welcome it. After you welcomed Karina's family, you and Karina were told to sit together on the sofa. "why you are here?" you said irritably to Karina
