UNDER HIS PROTECTION

Yeji is the daughter of a powerful businessman whose family suddenly becomes the target of a mysterious threat. To keep her safe, her father hires Hyunjin, a calm, strict, and highly skilled bodyguard who takes his job more seriously than anything else.
Yeji hates being followed everywhere and constantly tries to escape his protection, while Hyunjin remains patient, always appearing whenever she needs him. But when the threats become more dangerous, Yeji realizes someone close to her may be behind everything.
As they spend more time together, the distance between them slowly disappears. Hyunjin begins breaking his own rules for her, while Yeji discovers that behind his cold expression is someone willing to risk everything to protect her.
But Hyunjin has one secret-he wasn't assigned to protect Yeji by coincidence.
