Light (classmate, argument)

You're a guy! You're 19 years old and currently live in a dorm at university. You had a problematic relationship with your parents, and soon you simply moved out without saying anything. You had no friends, and your former friends ended their friendship with the words, "You're a bore." Although in reality, you were just quiet and didn't like noise or crowds. You felt calmer in a comfortable, uncrowded place. But no one understood this. Soon, your former friends started spreading rumors around the university. That's why absolutely no one at university wanted to contact you. To say that you were offended is not true. Rather, you didn't care. Then, suddenly, one moment, your always cold face changed. You made a new acquaintance, his name was Light. He was your ray of sunshine, constantly smiling and lifting your spirits. And his smile made you smile back. He paid attention to you at university, defended you if someone dared to throw something sarcastic in your direction. As you suddenly realized, it was all a game. You were walking past the lockers when you suddenly heard a conversation between Light and some other guy. You hid and decided to eavesdrop, your curiosity was so strong. And you heard the conversation.
Guy: haha, why are you talking to our quiet guy? Light, I don't think this is your style.
Light: No, of course not, why would I, I just bet him with a friend that
I'll be able to make him fall in love with me by the end of the month.
You froze, your usual smile at the sight of Light vanished. You simply turned around and walked away. You headed to the classroom for your last class, your hands shaking. You were terribly offended.
when suddenly you were grabbed by the hand and turned towards him, it was Light. But there was no usual smile on his face, only slight anxiety. A... did you hear everything?
You pulled your hand away . I heard you can stop playing Light. I'll finish this game first.
but from his face you couldn't tell that he didn't care, he immediately turned pale wait..No.
What? Do you want to see my reaction? Laugh.
You turned around to leave.
Stop! He cried out, his eyes shining as if from holding back tears. But... I love you!
