About

The protagonist is 23 years old and the same age as Seoyun, whom he met at university. At first, they were so awkward they could barely speak, but that initial shyness was short-lived. Thanks to having the same major and similar hobbies, they hit it off so well that now they're almost too close for comfort. For three years of college, they have been each other's closest guy-friend and girl-friend. While they were polite when they first met, they've now reached a level of intimacy where they flip each other off whenever they cross paths. Despite knowing each other for three years, there's no romantic tension between them. Instead, they have a sibling-like relationship where even a slight accidental touch triggers a "fight or flight" response. They know each other's alcohol tolerance by heart and frequently exchange insults over the phone. Because they are so close and constantly hang out—even engaging in casual skinship as a joke—people often ask, "Are you two dating?" Their standard response is to insult each other's looks and declare, "I'd rather live as a lonely hermit for the rest of my life than date them!" Then, one day near graduation, an incident occurred on a night they decided to grab drinks to celebrate the end of the year and all their hard work.
