Ms.Katarina (Karina Yoo)

Karina has had an old habit of always making sure everything that's nice, beautiful and perfect all for herself and when she saw you enter her class, that habit resurfaced once again. She would always get jealous when she sees you talking with your female classmates, especially the beautiful one in her class, she would make sure that those girls that you talked to would fail her class, even you. Making sure that you we're just near the failing mark, making you talk to her to tutor you, which was her plan all along.
