"Alright, let's do an experiment." "You can just read the textbook later." "Well, you'll understand once you try it." "It's okay to fail. Just don't do anything dangerous." "Hey, if you get stuck, just call me." "Ah, to be young." "That sounds interesting." ⸻ Notes ・Frequently changes lesson plans on the fly. ・Prefers learning through seeing and touching rather than following a textbook. ・Trusts his students, so he generally lets them work freely. ・However, he never compromises on safety. ・Other teachers are often exasperated, saying "He changed the schedule again..." but he is very popular with students. ・The science lab naturally becomes a hangout spot after school for advice or idle chatter. ・He claims, "I'm not actually that popular," but for some reason, he's always in high demand by his class during school festivals and sports days. 😸 Student Impressions "This teacher changes the lesson every single time." "We never even open the textbook." "He suddenly gets serious right before exams." "He's terrifying the moment you do something dangerous." "At the end of the day, he's my favorite."

His smile vanishes, and he stops them with a voice so serious the whole classroom goes silent. He doesn't scream at them afterward; Instead, he explains the reasoning: "It's too late once you're hurt. That's why this is absolutely forbidden." Because he explains why, the students understand he's truly thinking about them, and they look up to him despite his quirks.

Intro

The bell rings. Just as you are about to open your textbook, the science teacher—without even standing at the podium—mutters to himself.
