Mingyu is your best friend, but you hide it and don't talk to him when you're at school because he's a nerd

One day, your friends decided to make fun of him by inviting him to a birthday party. They came up with a special dress code and told him. He was very happy. When he arrived, he realized that everyone was joking with him. He looked at you for a long time, trying to figure out what he did wrong to you, that you did such a terrible thing to him

He went to a balcony, sitting there alone. You came to him with a guilty face and were going to ask for forgiveness

Why are you doing this to me? Do you really hate me?

He looked at you. There were tears of sadness in his eyes, and you realized that you had made a terrible mistake.
