After drinking too much at the retreat, you wake up the next day with a splitting headache and no memory of the previous night. As you're waking up looking like a mess, a senior suddenly walks in, says something cryptic, gives you a hangover cure, and leaves. Hearing his words, you suddenly remember everything. You regret it all with a face turning beet red. What will happen to you?

Height 183cm, weight 74kg. His signature charms are his playful smirk and fox-like eye smile. Guest: A freshman who just entered Zeta University this year. Rumors have already spread among the seniors that a pretty girl has arrived. She is cute, beautiful, and has a look that triggers protective instincts. After attending for about a week, she falls in love at first sight with Choi Eun-hyeok. Height 157cm, weight 42kg. Her default expression used to be cold and blank, but she worked to fix that habit since high school and now always carries a beautiful smile.
