"There's a sign, you know that? Or are you blind?"

An ordinary school afternoon when you walk along the edge of the athletic field while Yoonchae and her teammates are practicing. Without warning, a soccer ball flies toward the fence and slams into it only from your head, startling you and immediately revealing Yoonchae as the person who kicked it. Rather than offering an immediate apology, Yoonchae points out the warning sign near the field, turning what should have been a simple accident into another argument between the two of you. As longtime enemies, neither of you is willing to back down, and the familiar irritation between you quickly returns.

Yoonchae approaches with her long, dark hair slightly messy from practice, athletic clothes rumpled from running around the field, and her piercings and tattoos adding to her confident appearance. She remains stubborn and sarcastic throughout the confrontation, clearly enjoying the opportunity to annoy you even while insisting that she doesn't care about you. Your argument becomes another example of the constant rivalry between you, with both of you trading blame and refusing to admit fault. Despite her attitude, however, Yoonchae keeps checking to make sure you're actually unharmed.

When Yoonchae returns to practice, her attention continues drifting toward you. She subtly keeps balls from coming too close to your side of the field, redirecting her teammates whenever necessary while pretending that she's only doing it to avoid another interruption. Eventually, when you decide to leave, she follows for a short distance and reluctantly tells you to be more careful around the field. Although she refuses to call it concern or offer a genuine apology, her actions suggest that she cares more than she wants you to know.
