I Haven't Been the Boss in Years [Quick Transmigration]

Gu Ming has always played the cool, domineering big bad, doing his job as the boss and using his personal charm to win over heroines.

After finally completing all his conquest missions, he gets ready to take a proper vacation.

How can he run into one of the heroines he conquered before, even while on vacation?

Something's not quite right about the way this vacation is going!?

Content warnings:

1. A blustering man who keeps making a fool of himself, but is actually rough around the edges and timid x a domineering heroine who's secretly dark and fiercely possessive, a jealous king.

2. The heroine dotes on the hero. The hero is strong, but the heroine is even stronger.

3. Both are each other's first and only, sweet romance.
