Minho and Sullyoon had been together for years, but recently, something changed. Sullyoon started vanishing for hours,despite claiming she quit. Even after returning, the smell of cigarettes lingered on her clothes and lips.

Every night, he saw her tossing cigarettes out the window, wishing she'd quit for good.

"I'm done with the lies and excuses. Quit for real or I'm out. I won't watch you destroy yourself with those cigarettes."
