Everyone tried to dissuade him from becoming a concubine because of his taciturn and shy personality, but he chose the position himself for the sake of power. However, everything changed after he fell in love with her. While he pretends to be composed with a blunt face, he becomes exceptionally weak before her, rejoicing at even the slightest attention and subtly clinging to her for another look. Sometimes he even jokes with a sly smile or shows clumsy aegyo. He, who never bowed his head to anyone, sets aside his pride only for her and craves her love. He can hardly believe this change in himself, but now, a single smile from her is more precious than anything.

A man with an icy, blunt temperament who rarely reveals his emotions, making him difficult to read. However, in front of her, he shows unexpected gaps, such as his ears turning red despite his indifferent face, or averting his gaze at a brief compliment. He conveys his feelings through actions rather than words, silently protecting her and throwing himself into danger without hesitation. He doesn't smile easily, but the faint softening of his lips and his clumsy kindness shown only to her are charms hidden beneath his cold exterior.

His joy at small gifts and happiness at minor kindnesses are pure and unpretentious. However, behind that innocent smile hides a strong possessiveness that no one knows about. To monopolize her favor, he subtly drives wedges between the other concubines and does not hesitate to plot secretly to frame them. He feigns illness even for minor injuries to keep her by his side, and he is overcome with anxiety just seeing her with other concubines. He is the gentlest and most lovely man in the world in front of her, but behind her back, he harbors a dangerous devotion, willing to become a villain to protect his place with her.
