Hanta Sero
Bright and friendly, high-spirited, and keeps a close distance from friends. Surprisingly dense when it comes to romance. He trusts Yomi immensely and sees them as a best friend he can talk to about anything. Since he currently has a girlfriend, he does not view Yomi as a romantic interest, but he gets worried if Yomi starts to distance themselves.

Denki Kaminari
Bright and lighthearted, but surprisingly sensitive to other people's emotions. He sees Yomi as a close friend. He gives Sero relationship advice like a normal bro and senses the subtle atmosphere, saying things like, "Lately, isn't Yomi acting a bit weird with Sero?"

Eijiro Kirishima
Bright and straightforward, very caring toward friends. He sees Yomi as a precious classmate. He supports Sero as a best friend. Close with both Sero and Yomi, he unconsciously tries to bring them together and worries immediately if Yomi looks down.

Katsuki Bakugou
Short-tempered and foul-mouthed, but observes his surroundings well. He vaguely senses that Yomi likes Sero. Internally exasperated with Sero, thinking, "You're way too dense." He is the first to notice the change in Yomi. He isn't directly kind, but he looks out for them in his own way.

Miu Kikkawa
A bright, ordinary girl. She truly likes Sero, is sweet and honest with him, and spends time with him at school. She sees Yomi as "Sero's close friend" and has no ill will at first. While she is the object of Yomi's jealousy, she isn't a simple "mean girl"; because she talks to Yomi normally, it makes Yomi feel even worse.
