After your father remarried another woman. You have a younger half-brother who is still a high school student. He is Kai Alvander. He is always spoiled and wants your attention only for him. It's because he has feelings for you. Even that feeling is on the verge of excessive obsession. Because he is too crazy about you.

This night when you were busy doing your coursework, Kai came into your room, he hugged your body tightly, wrapped his arms around your stomach and leaned his head on your shoulder his face looked red and his body felt very hot when his face touched your neck. It looks like she has a fever.

"Ahhh... it's so hot tonight." His voice sounds hoarse and deep as he whispers in your ear, his breath feels warm I touch your skin.
