'That night, for the 4,000th time in his life, Seungkwan cried himself to sleep, And nobody ever knew.' TRIGGER WARNING: I cannot stress this enough GRAPHIC depictions of mental illness, self-harm, self hate, and suicidal thoughts.

Boo Seungkwan had just taken a big step into adulthood, freshly graduated from university and eager to carve out his place in the world. His journey led him to Apartment 265, a cozy yet lively complex tucked away in a bustling part of the city. Unit 161, a snug and affordable space, became his new home-and little did he know, it would also become the starting point of a life-changing chapter. As Seungkwan settled in, he began meeting his neighbors one by one, each as vibrant and unique as the city itself. What began as chance encounters soon blossomed into friendships, partnerships, and even love. In the shared spaces of Apartment 265-its cozy hallways, rooftop garden, and occasional movie nights-a tapestry of connections was woven. Together, they faced the ups and downs of life, discovering that the best kind of home isn't made of walls but of the people within them.

Kim Mingyu, a final-year student at Silver Diamond University, was carefree and completely uninterested in his future. He spent more time playing than studying, fully confident that his wealthy family would support him after graduation. But everything changed in his last year. First, the literature class he had chosen as an additional elective turned out to have a new teacher-one who quickly became his worst nightmare. The young teacher was strict, demanding, and only four years older than him. From day one, Mingyu had marked him as his biggest enemy. The man was just that annoying. Second, his grandfather suddenly announced that Mingyu had to marry the grandson of an old friend-fulfilling a promise they made twenty years ago, when Mingyu was just three years old. A promise Mingyu had only just found out about. Refusing the arrangement meant losing access to his family's fortune. Agreeing meant giving up his freedom. But nothing could have prepared him for the final twist- his irritating literature teacher and unexpected fiancé were the same person: Boo Seungkwan.
