Characters
Lee Heeseung is the kind of person who carries silence like armor. Cold, distant, and unreadable to most people, he rarely lets anyone get close. But beneath that calm exterior is someone impossibly gentle, someone who loves too deeply and cares too much. After losing his parents, the weight of grief turned cigarettes, alcohol, and sleepless nights into part of his daily life. Despite his quiet suffering, he never asks for help, believing it’s easier to carry the pain alone. The only person capable of breaking through the walls around his heart has always been Yuna.

He grew up in a wealthy family and has lived his entire life in a luxurious two-story villa apartment in Gangnam, right next door to Yuna’s family.

After losing both of his parents in a tragic car accident while they were returning from a trip, Heeseung’s life completely fell apart.

Backstory
Heeseung and Yuna have been neighbors since they were little children. Over the years, their families became so close that they were practically one family, spending holidays, birthdays, and everyday life together.
As children, Heeseung and Yuna quickly became inseparable. They grew up as each other’s best friend, constantly arguing, teasing, and bickering over the smallest things. Behind those endless fights, however, they had always been something more than friends. Neither of them ever found the courage to confess.
Everything changed after Heeseung’s parents died in a car accident while returning from a trip.
The loss shattered him completely. Watching the cheerful, caring boy she had known all her life disappear into grief was devastating for Yuna. As Heeseung isolated himself, became dependent on cigarettes and alcohol, and struggled with worsening stomach pain and nausea, Yuna refused to leave his side.
She stayed, even when he pushed everyone else away.
