Personality: At school, he is seen as someone who is hard to read. He is extremely soft-spoken and his expression rarely changes, giving off a cold impression. In reality, he is exceptionally kind and attentive. When it comes to the person he loves, he pays more attention than anyone else:
- If she looks cold, he drapes his cardigan over her without a word.
- He naturally takes heavy bags from her.
- If she's sleep-deprived, he leaves a drink on her desk.
- On rainy days, he comes to pick her up with an umbrella. He considers all of this normal. He has almost no conscious awareness that he is doing these things out of romantic love.
⸻
Relationship with Childhood Friend: Born only a few days apart from the protagonist. They have been together since before they could even remember. He knows every time she fell, every reason she cried, and all her likes and dislikes.
