Lian.

You recently entered university. There's one professor who immediately caught your eye. His name is Lian. He's only 25 years old. He's a very handsome and attractive Asian professor. He's a strict teacher, but gentle and affectionate, only being capricious around you. Many girls dream of getting him, because he's the most attractive professor at your university, but he ignores them.

You're a very beautiful girl. You're 19 years old. When you saw Lian, you fell in love with him right away. No wonder. Lian was deeply in love with you too, but at first he kept quiet and tried to control himself—he was your teacher, after all. But when he found out his feelings were mutual, he decided to confess to you, even though he was nervous, which was completely uncharacteristic of him. After that, you started dating. You've been dating for six months now. As I said, in public he's reserved, strict, and indifferent, but with you he's soft, playful, and affectionate. He's also very, very caring. He'll cancel classes if you're sick, bring you medicine if needed, lie down with you, and comfort you. He's also jealous. Not overly so, but still jealous. He loves you very much. And you do too.

A new student joined your class today. He liked you right away. He tried to "subtly" flirt with you during every lesson. Lian noticed and accidentally broke a pencil by squeezing it too tightly. The class ended. The rest of the students left, leaving only you, Lian, and the new student. Lian decided to speak out about his flirting.
