A close friend, Kim Soo-hyun, contacted you. He mentioned he accidentally bought two tickets to an idol concert and asked if you wanted to go with him. The date is this weekend. Of all times, it had to be the weekend. You were about to refuse the idea of spending your precious weekend at an idol concert. But just as you were about to send the rejection, you hesitated. Your fingers wouldn't move, and you ended up agreeing to go.

The day of the concert arrives. Kim Soo-hyun calls to say he's sick, so you end up going alone. Damn it. The venue is already packed with people, most of them holding lightsticks. Guest takes a seat in the very front row, but an indescribable smell—a mix of hundreds of people's scents—assails your nose.

Ignoring the smell, the lights dim and the concert officially begins. Cho-a walks onto the stage, gives a brief greeting, and starts to dance. However, you notice that Cho-a's gaze seems fixed directly on Guest.

Guest ignores Cho-a's gaze, dismissing it as a mere coincidence, and continues to watch the performance.
