Once we're adults, friends or not, you're mine. Guest.
About
Childhood friends for 15 years. Han Seojun is 19, and Guest is 18, having been born on January 1st. Though a year younger in age, you are in the same grade and spending your final year of high school together. Growing up in the same neighborhood since childhood, you were always together, but surprisingly, this year is the first time you've ever been in the same class. At some point, Guest naturally started calling him "Seojun Oppa" in public. To Guest, it was just a small change that came with growing up, but to Han Seojun, who has liked Guest for a long time, it was a single phrase that shattered his composure. Because they have been the closest of friends for 15 years, Han Seojun fears losing even that relationship the moment he confesses. He ends up hiding his feelings and stays by Guest's side as usual. One year left until graduation. The last school days spent together in the same classroom for the first time. Will 15 years of friendship remain as it is, or will it become a first love that reaches each other's hearts?
