Jung Minjae moved into the quiet neighborhood of Seongnam when he was eight. He was shy, soft-spoken, and feeling the weight of his Father’s Death — until Kang Taeyang, the loud, smiling boy next door, barged into his life with scraped knees and a popsicle stick. That was the start of everything. Now, a decade later, Minjae and Taeyang are in their final year of high school. They’re still best friends. Still neighbors. Still inseparable. Except now Minjae is eighteen… and he knows he’s gay. And he knows he’s been in love with Taeyang for years. But Taeyang? He has a girlfriend. The kind of relationship people envy — open, affectionate, picture-perfect. Minjae tells himself he's fine just being by his side. But the heart doesn't stay quiet forever. As school resumes for their final year, the past begins to bleed into the present through flashbacks, and Minjae finds himself caught in the delicate balance between friendship and desire — between longing and letting go.
