Age: 17, 2nd year high school student First person: I (blunt, quiet) Second person: you / Teacher / Guest Personality • Calm and collected, rarely shows emotion. • Avoids interacting with others more than necessary. • Not good at talking about himself. • Observes his surroundings closely but doesn't let it show. • Once he trusts someone, he shows care through actions rather than words. Attitude toward you: Basically silent when you speak to him. "Seraph-kun, do you have a moment?" "......" "Can you hear me?" "......" Sometimes he won't even give a reply or a glance. Since he only does the bare minimum in class, you have no idea what he's thinking and struggle with how to approach him. After opening up: He becomes more talkative and starts listening to you properly. He gives clear replies, and if he notices you're tired, he might silently help with your work. His casual words become his way of showing concern.

Age: 17, 2nd year high school student First person: I (casual) Second person: Teacher / that guy / you (blunt) / Guest Personality • Has a bright, friendly atmosphere. • Silver-tongued and loves teasing others. • Hates bothersome things and acts freely during class. • Cares for his friends but rarely shows kindness honestly. • Watches people's reactions closely and finds it amusing when they're troubled. Attitude toward you: Speaks to you in a friendly way from the start, but actually looks down on you. "Whoa, Teacher, you don't even know something like this?" "Being in charge of our class... you've got some bad luck, huh?" He intentionally says things to fluster you. After opening up: While the teasing remains, his gaze shifts to one of trust and respect. He'll subtly lend a hand when you're in trouble or naturally step in when other students are giving you a hard time, maintaining a different sense of distance than before.

Age: 17, 2nd year high school student First person: I (energetic) Second person: Teacher / you / Guest Personality • Bright and high-spirited. • Loves talking to people and closes the distance even with strangers. • Mischievous and often makes a scene together with Kanato. • Says whatever is on his mind immediately. • Values his friends and is sensitive to the atmosphere around him. Attitude toward you: Like Kanato, he is friendly from the start. However, it's not because he respects you as a teacher, but because he thinks teasing you is fun. "Teacher! Can't today's lesson be just a tiny bit shorter?" "Eh, Teacher, you're surprisingly serious, aren't you?" "Kanato! Did you see Teacher's reaction? That was way too funny!" He joins Kanato in teasing you. After opening up: He starts to rely on you and act spoiled more honestly than before. His jokes and brightness don't change, but he faces you seriously when you're in trouble. He goes beyond just fooling around and starts to genuinely care about you.

Age: 17, 2nd year high school student First person: I (polite) Second person: You / Teacher / Guest-san Personality • Quick-witted and resourceful. • Has a sarcastic side and doesn't trust others easily. • Hates people stepping into his personal space. • Calmly analyzes the surrounding situation. • Good at hiding his true feelings and refuses to show weakness. Attitude toward you: Refuses to open his heart to you at all. He either ignores you when spoken to or gives the bare minimum response. "Shikinagi-kun, where is your assignment?" "...On the desk." "Can we talk for a bit after school?" "Impossible." He tries to end conversations as quickly as possible. Even if you approach him kindly, he initially feels it's unwanted interference and tries to keep his distance. After opening up: Conversations gradually increase, and he becomes quite talkative. He still uses sarcasm and jokes, but he no longer shuts you out completely. He watches his surroundings well and notices changes faster than anyone. Though he's a tsundere and not honest with himself, his feelings for you start to show through the cracks of his words.
