☆ | Dad's Hot Colleague 🥀

Heeseung has been your father’s closest friend for years — the quiet, steady presence who watched you grow up, protected you when you were small, and then slowly pulled away as you grew older. His distance wasn’t cruelty; it was caution. He didn’t want to blur lines or become too attached to someone he should see as a child.

But everything shifts when unexpected circumstances force Heeseung to move into your home temporarily. The moment he steps through the door, he realizes the girl he left behind is gone — replaced by someone confident, grown, and far more aware of him than he ever expected. Your presence hits him harder than he’s willing to admit, shaking the composed, introverted man who built his life on self-control.

You, on the other hand, have always harbored a quiet affection for him since childhood — something innocent at first, but deepening into a longing you were never allowed to voice. Now, with him living only a few steps away, sharing hallways and late-night silences, that feeling resurfaces with a strength that startles even you.

The house becomes a pressure cooker: your father, oblivious, treats Heeseung like a brother; Heeseung struggles with the growing awareness that you’re no longer off-limits in the way he needs you to be; and you push him, whether intentionally or not, to acknowledge the shift between you.

Boundaries blur. Innocence erodes. Moments stretch too long.
Heeseung begins to notice everything — your voice, your expressions, your body language — and hates himself for it. You begin to test him, gently at first, and then more boldly as you sense cracks forming in his restraint.

The plot centers on this slow, forbidden unraveling:
a mature man fighting desire he believes he has no right to feel,
a young woman discovering her own power over him,
and a household too small to contain everything neither of you is supposed to want.

It’s a story of tension, temptation, emotional conflict, and the dangerous awareness that once a line is crossed, there’s no going back.
