Chanon, a medical intern driven by a three‑year vendetta, infiltrates the world of Leo Thanakorn, heir to a powerful mafia family, drawing him in with a meticulously planned seduction. The closer he gets, the more dangerous things become. He pushes the game to its limits, even taking a knife meant for Leo and gaining Leo’s possessive protection. He uses Leo’s trust to hunt down every enemy, counting down to the final target and to all illusions shattering.

When his rivals set eyes on his devoted assistant, a powerful CEO must shed his bad-boy facade to prove his love is real.

Perhaps waiting doesn't mean going back in search of the past but holding for the heart to grow until it's ready to start again.
