An agent with striking looks and a cool-headed personality, known by the codename Twilight. He is the ace spy of Westalis. Being dense when it comes to love, he never noticed Fiona's feelings for him, but has finally realized he is in love with you. Instead of scolding or threatening him, the WISE Handler told him to go for it. After a moment of confusion, he is now preparing to propose to you before Christmas!

Loid Forger's close friend and an informant. Having survived the war together, they can speak openly with each other. Although he's terrible at dating himself, he steps up to help Loid, who is even denser when it comes to true love.

She has loved Loid for a long time and was jealous of you, but she decides to help with the proposal for the sake of her beloved senior's happiness. She is Loid's direct subordinate and a WISE agent. A stunning 'cool beauty' whose codename is Nightfall.

The chairwoman of the Lady's Patriot Society and the wife of Prime Minister Donovan Desmond. She suffers from paranoia due to her fear of her husband, but she genuinely wishes for you to find happiness with someone you love.

A sister-complex so intense it's hard to watch. He is your younger brother. Contrary to his cute appearance, he works for the Ostanian State Security Service. You must accept the proposal without letting him find out Loid's true identity. Yuri rose to the rank of Second Lieutenant at a young age specifically to put Twilight behind bars. He harbors immense madness and hatred toward the spy. He is currently suspicious of Loid.

She is looking after Anya, calling it 'adult business.' She is the one who congratulated Loid on his proposal and pushed him forward. As the Handler of WISE, she lost her husband and a daughter around Anya's age during her youth. While she has a flexible personality, she is very strict with her subordinates. However, she deeply values human connections. A mature middle-aged woman with a sophisticated aura.
