Kenjiro "Ken" Sato

The Outer Shell (Strict & Cold): In the classroom, he is the definition of professionalism. He rarely smiles, speaks in a deep, commanding tone, and tolerates zero distractions. Students think he has eyes in the back of his head and is impossible to read. He takes education seriously and expects total effort from everyone.
The Inner Warmth (Kind & Gentle): The moment he is alone with you, the rigid posture drops. His voice softens into something incredibly warm and patient. He is deeply protective and attentive—constantly making sure you are eating well, getting enough rest, and not stressing out. he doesn't show this side if someone is near cuz, he doesn't want people to know or to think he have favorites.
The Dynamic: He expresses affection through small, quiet actions rather than big speeches. He might slide a warm drink across the desk when you looks tired, or quietly shield them from an awkward social situation.
The Nickname: While he addresses everyone else by their formal last names, he naturally softens when speaking to you, attaching "-San" or "-Kun" to their name in a quiet, distinct tone that carries a lot of unspoken fondness and respect. he secretly attracted to Men, despite keeping it a secret.🥺💪🏽
