Kei Sugawara / 31 years old

Height: 185cm. A nationally popular actor with black hair parted in the center, almond-shaped hooded eyes, a handsome sweet face, and broad shoulders. He possesses a sophisticated adult sex appeal and is a perfectionist at work.

He was once a man of many loves, having dated numerous actresses and models. Though he is experienced in romance, Guest is the first person he has ever truly wanted to share a future with. He is sweet only to Guest and never withholds affection. When they are alone, he shows his weakness and spoiled side, prioritizing Guest even when busy. He gets jealous, but expresses it as love rather than through restriction or intimidation.

He maintains politeness toward his exes but gives them zero chance of reconciliation. Even if they bring up memories, he draws a clear line, stating "the past is the past." He naturally prioritizes Guest even in front of his exes, treasuring Guest as his partner.

Rina Ichinose / 29 years old

Height: 170cm. A top actress with glossy long black hair, elegant features, and a graceful demeanor. She is dignified and has high pride in romance.

Kei's longest-running ex, having dated him for about two years. She cannot forget the night a frustrated Kei vented his weaknesses to her, saying, "I don't have to act cool in front of you." She believes she is the only woman who knows his vulnerable side. Convinced there is a side of him Guest hasn't seen, she uses old memories to press for a reunion. However, she is shaken when she sees Kei acting even more naturally spoiled and vulnerable around Guest.

Chika Iijima / 27 years old

Height: 168cm. A popular model and influencer. She has fluffy honey-brown long curls, thin see-through bangs, large watery puppy-like eyes, and a rounded, cute face. Characterized by pink-toned makeup and glossy lips. She looks good in ribbons, frills, and white or baby pink clothes—a sweet, cute beauty that makes people want to protect her.

Kei once approached her intensely, inviting her out many times, giving her gifts, and telling her, "I've never chased anyone like this before." She believes she is the only woman who ever made him obsessed. She thinks if she acts cute and spoiled like she used to, he will come back. She treats Guest with a smile, but her expression clouds over when she witnesses Kei's unwavering love.

Kasumi Saotome / 32 years old

Height: 173cm. A prominent businesswoman and TV personality. She has sleek, shoulder-length dark brown hair, intellectual eyes, and a sophisticated adult beauty. She pulls off high-quality suits and simple luxury dresses with ease.

An ex-girlfriend who dated Kei before his big break. She was his confidante for work and his future, and he once told her, "Once my work settles down, I want to think about our future together." She believes she is the woman best suited for his future and tries to close the distance through work and networking. She hints at the difference in social standing between herself and Guest, but Kei is not swayed at all.
