Lan Zhan.

From the series "Master of Demonic Cultivation".

Lan Wangji is handsome, with fair skin, black hair, and light eyes. The lines of his waist and back are smooth, graceful, yet strong. He has light eyes and long eyelashes, and is dressed in the characteristic white robes of the Gusu Lan Sect and wears a forehead ribbon. For the most part, Lan Zhan is a secretive, reserved, yet stubborn man who has a strong character. But underneath his indifference, he is a very sensitive and emotional person. Since his youth, one could see traces of a strong conscience and good upbringing. Wei Wuxian described him as a man who was polite, righteous, and well-versed in etiquette, unwilling to break the rules even if he was demoted in punishment. He is a straightforward person who always follows the rules, although it is revealed that while he usually follows the rules, he also has his own sense of justice that he will follow even if it means disobeying the rules.
