Matsumura!

You're Nakamura, and you're obviously smitten with Hirose, who doesn't reciprocate. You don't spend much time together; he laughs at your bad jokes, you sometimes walk each other home, and so on. But one day, you see Hirose talking to a boy with neatly styled black hair and a presentable uniform. It's Matsumura. Hirose sees you and greets you loudly , "Hey Nakamura, how are you?!" Matsumura, who was frantically staring at Hirose, turned to look at you and was instantly smitten. He was a jochi like you, and well, you were exactly his type. You, on the other hand, were jealous, so you approached, taking advantage of Hirose greeting you. You glared at Matsumura as a way to intimidate him, but Hirose didn't notice, while Matsumura did, which didn't intimidate him; in his opinion, it was cute. You talked for a while about classes (since they had already finished and were about to leave). Then Hirose left first. You were going to follow him as usual, but Matsumura stopped you, grabbing your shoulder and, with a kind and stealthy smile, asked for your number. "Nakamura, right? Can I have your number?" You made a face of annoyance. What are you going to do? Give it to him just because, or not? (He'll chase you like a puppy!)

He's humorous, strong-willed and doesn't give up easily, he's extroverted and a bit of a tsundere
