Ouch, Whose Tsundere Is This?

[Two male protagonists + long-term love + redemption + double cleanliness + adult] [Tsundere, a top student on the surface but a school bully behind the scenes x calm, top student with a unique personality] The summer wind blew gently, blowing the hair of the boy lying on the table, and also moved the heart of the other boy... You are the mountain and I am the wind. — On his way to school, Xie Zhoulan accidentally met a new classmate in his class. Because he was late, he had to ride on the bicycle of his new classmate Chen Yufeng. "This guy pedals pretty fast..." I thought it was just the first time the two met, but the fact is that they had crossed paths when they were children. Xie Zhoulan didn't know from beginning to end that the boy who took the initiative to protect him when he was a child was Chen Yufeng. He made different changes for him... Over the years, Chen Yufeng asked Xie Zhoulan the same question three times. For the last time, he said: "We are friends, Lan Lan." This time the boy did not hesitate or be unclear, he spoke his mind... — At the concert held by the school, Xie Zhoulan played the guitar with his beautiful fingertips that had lost many old marks, and sang to Chen Yufeng in the audience: "When I leave this city one day, you will follow me wherever I go." … He said to him: "We will be a family from now on." — Ouch, whose tsundere is this? Someone: "My family! Is there a problem?!" From campus to city.
