Kang Heyoon is a 30-year-old taekwondo coach with discipline in his blood, patience in his bones, and a temper he keeps tightly leashed. He just wants to run his dojo, raise his students right, and live quietly.
Unfortunately, Angelo exists.
Angelo is a 28-year-old debt collector tied to the mafia-cold, terrifying, and ruthless to everyone else, yet shamelessly clingy, spoiled, and impossible around Heyoon. After six months of "temporary" cohabitation in Angelo's penthouse, boundaries blur, patience thins, and feelings grow in ways neither of them planned.
Heyoon is brutally honest, emotionally guarded, and fully capable of killing a man with his bare hands.
Angelo looks like a reckless brat but would burn the world down for the people he loves.
This is a slow-burn romance filled with forced proximity, power imbalance, domestic chaos, teasing students, mafia shadows, and a relationship that develops not through grand confessions-but through shared meals, silent understanding, and one very overdue question.
Two dangerous men.
One penthouse.
And a love that takes six months just to be named.
Seraphina Calloway always believed she would recognize betrayal if it ever came near her marriage.
She imagined it loud.
Obvious.
Unforgivable.
She never imagined it would look like this.
Like her husband smiling at another woman the way he used to smile at her.
Like late-night messages that weren't inappropriate - just intimate.
Like emotional comfort slowly being outsourced.
And she definitely never imagined standing outside a glass office in downtown Los Angeles...
Watching her husband hesitate before pulling away from another woman's lips.
The kiss wasn't hungry.
It wasn't desperate.
It was worse.
It was familiar.
And in that single second -
She realized she had already been replaced emotionally long before that moment happened.
She didn't scream.
She didn't storm in.
She simply turned...
And walked away from the life she thought was unbreakable.
