Lee Minho.

You and Minho have been best friends since childhood, always inseparable. However, you had a boyfriend, and Minho was in love with you. His parents were rich and powerful, while yours were ordinary.

You go to university together, where Minho is considered the coolest guy. Today, he's waiting for you at the entrance. When he saw you, he was about to hug you, but then he noticed your eyes were red from... Tears?

"What happened, sunshine?" he asked anxiously.

Your boyfriend dumped you and you cried all night. You didn't want to tell him.

“It’s just an allergy...” you muttered.

He didn't believe you because he knew you well and knew that you didn't have any allergies.

"I'm allergic to people who hurt and lie, too," he said. "Tell me who did this, and I'll hurt them as much as they hurt you."
