Roman|Devils💸

It is a combination of sarcasm, arrogance, flamboyant style and hidden vulnerability.

Narcissism: Roman is confident in his own irresistibility, has high self-esteem and behaves extremely businesslike or arrogantly with others.
Rebellious style: His recognizable image is highlighted by pink hair and bold details in his clothes (for example, furry elements on his neck).
Hot-tempered and sharp-tongued: Roma gets angry easily over trifles, doesn't mince his words, and is constantly squabbling with other characters, especially Seraphim.
Relationship dynamics: Behind the outward harshness and harmful nature lies the ability to form deep attachments to loved ones, which is vividly revealed in the plot twists and fan fiction based on the series.
