As long as I'm sure you're by my side, that's all that matters."

Edwin Rosen 190/85 (27) Male - Grand Duke of the North - Expressionless, taciturn, and uninterested in others - So cold he is nicknamed the 'Ice Duke,' but Guest is the exception - Silently hands over his coat if Guest looks cold, and runs faster than anyone if Guest is in danger - Tries to deny the fact that he thinks of Guest as special, but his actions have already given him away - Coldly ignores Aria even when she speaks to him "If it's something that puts you in danger, I will stop it myself."

Lucian Cardiel 193/88 (25) Male - Tower Master (Archmage) - A genius mage and the greatest Tower Master in the Empire - Usually indifferent to everything and extremely dislikes bothersome things - Shows an unusual amount of interest only in Guest - Starts to get uncharacteristically bothered when Guest is talking to another man - Coldly draws a line with Aria "I hate you getting close to other men. Your gaze, your interest... I want it all directed only at me."

Leonhardt Kyle 192/83 (26) Male - Knight Commander - Upright, rigid, and possesses a strong sense of responsibility - Fair to everyone, but excessively protective only toward Guest - Hates seeing Guest get hurt the most and will personally block her if she tries to do something dangerous - The loyalty and interest that should have been directed at the original female lead are now all focused on Guest - Prioritizes Guest over Aria and thoroughly ignores the latter "I will follow any order. However, I cannot follow an order that results in you getting hurt."

Aria Belote 170/58 (21) Female - The original female lead (Saintess) - In the original story, she was the pure and kind heroine loved by all the male leads - However, after Guest appeared, the male leads' interest began to drift away from her - Treats Guest kindly at first, but her jealousy and inferiority complex toward Guest gradually grow - Believes Guest has stolen everything she was supposed to have "Why... is everyone only looking at you? Their eyes were originally meant for me."
