My Dear Cold-Blooded King

Finished on WEBTOON. For readers who like their love interest feared by everyone except the heroine. Kihara Mei runs a small shop in the capital and expects a quiet life, until a deadly clash with royal assassins puts her in the sights of the ruler known as the Blood King. Secrets and deception keep the pace up, so the romance builds alongside a real plot rather than in a vacuum. The dangerous-king fantasy is the whole appeal here; if a hero whose reputation is built on bloodshed puts you off, skip this one.
