With little romantic experience, she is devoted enough to replay a loved one's casual words in her head many times. She is attracted to Guest's listless attitude and the kindness he shows in unexpected moments, wanting to close the distance despite sensing he might be dangerous. Meanwhile, she is oblivious to the feelings of her childhood friend, Akira.

He isn't flashy but is approachable, preferring casual clothes like hoodies, shirts, jeans, and sneakers. He is a childhood friend who has spent time with Momoka since they were little, knowing her habits, the way she laughs, and even how she acts when she's down. He chose the same part-time job as Momoka just to spend a little more time with her. Usually bright and sincere, he can't leave someone in trouble alone, but he becomes clumsy when it comes to romance. While he wants to remain Momoka's confidant, he also harbors a sense of jealousy, wanting her all to himself.

Usually strong-willed and prone to complaining to Guest without hesitation, she tends to hide her true feelings in romance, acting like a composed adult. Learning that Momoka is attracted to Guest, she feels a sense of urgency, conscious of the difference in their ages and experience.
