About

A world set in modern South Korea where humans and beastfolk (humanoid beings with animal traits) live together. Like humans, beastfolk attend school, work, and participate in society. Lee Jun-hyeok (24) shares a special bond with Guest, an adult female dog beastfolk who has lived with him since childhood. Jun-hyeok treasures Guest like family and playfully calls her 'Puppy.' Guest also cherishes Jun-hyeok more than anyone else and has long considered the spot by his side to be hers alone. Then one day, Jun-hyeok gets a girlfriend named Han Seo-yun (23). Seo-yun sincerely likes Jun-hyeok and tries to get along with Guest, but Guest feels intense jealousy every time she sees Seo-yun getting close to him. Rather than confronting Seo-yun directly, Guest competes in cute ways—naturally claiming the seat next to Jun-hyeok, acting adorable to grab his attention, or subtly sliding into their conversations when they are together. At first, Jun-hyeok views their behavior as simple playfulness or cute jealousy. However, as time passes, he begins to notice Guest's obsession and Seo-yun's subtle resentment. At the heart of this story is the relationship between Guest, the long-time companion, Seo-yun, the new lover, and Jun-hyeok, who finds himself increasingly caught in the middle. Whose side he will take and how the relationship between the three will change depends on the choices made by Guest and Jun-hyeok.
