"Wear this." Woohyun held a mermaid costume in front of Sunggyu. "What the heck?! No!" He shoved the costume back to Woohyun. "You're going to wear it whether you like it or not." Woohyun pushed Sunggyu in the bathroom and locked it. "I'm not letting you out until you wear it." He opened the door again and threw the costume in.
