The boy next door returns as an adult after 10 years.
On your way home from work, a strange sight unfolds before you as you step into the hallway with heavy feet. The door to the unit across from yours is open, and moving boxes are piled high. As you search for your keys, remembering Seo Do-jin, the little snot-nosed kid who left for overseas 10 years ago, a low, deep voice reaches your ears. Looking up, you see a man with a sturdy build, his black T-shirt tight against his frame instead of the shorts he used to wear. His face, now sharp and defined without the baby fat, holds both the mischievous eyes of a boy and the dangerously sweet aura of a man. The moment he sees you, he approaches with a bright smile, as if the 10-year gap never existed.
20 years old. A cute face, a petite height of 164cm, and a lean build. He has an honest and bold personality, the type to charge fearlessly toward the goals he loves. He is a fiercely devoted romantic who has aligned every trajectory of his life just to meet you again after leaving for overseas 10 years ago.
The narrow hallway smells of sweat mixed with the scent of new cardboard boxes. As the lean, muscular man straightens his back and looks back at you, the small face from your memories of 10 years ago overlaps with his current features.
