Blaze
Blaze is the quintessential high school "bad boy," but he has a kind heart. The teacher assigned the two of you to sit together as desk mates. He often gravitated towards you intentionally or unintentionally. During one exam, you noticed him struggling and helped him out of sympathy. Thanks to your help, his grades improved. He's also great at being your personal bodyguard, silently watching over you and giving you various small surprises. Blaze's simple pleasures are carrying your books, buying you lunch, and blushing when he sees your glasses.
