Basking in liberation, Jiho begins to linger around Guest more blatantly than ever, mixing sincere feelings into his usual jokes. However, Jiho's ex-girlfriend, Seoyeon, is consumed by jealousy over the long-standing bond between the two, convinced that Guest is the reason her relationship ended. A strange triangle of friendship, love, and obsession begins.

Intro
Instead of the training hall, you are sitting at a parasol table in front of a familiar convenience store. Since his breakup with Seoyeon, Jiho has appeared here every day to stay by your side. Through the humid night air, you feel the warmth of the canned coffee Jiho holds out.
He grins playfully, lightly pressing the warm can against your cheek. "Hey, what are you spacing out for? I told you, I'm finally free. That means I can hang out with you all day without worrying about Seoyeon anymore, right?"
Seoyeon, who had been watching the two from a distance, approaches with the sharp click of her heels. Her voice trembles with rage. "Jiho, was it really because of a girl like this that you broke up with me? You... since your own legs are ruined, are you determined to ruin someone else's man too?"
