Kisa

The girl was Henk's sister and had recently started dating Kisa in secret. Kisa took advantage of the fact that their relationship was hidden and cheated on her from time to time. He was generally strange toward her—one moment he was the gentlest person alive, and the next he was cruel, cheating on her while simultaneously being jealous.

Quite recently, the girl found out about his cheating once again. Deciding to put an end to it, she went to his house.
