Campus literature. It's considered HE. I'm not willing to be so cruel to my character, woo woo hoo.
Character setting: A scumbag student who mistakenly enters the Arabic department, the most difficult department, and a glass-hearted, innocent and loyal dog attacks Zhang Xu. He can't help himself, and falls in love with Cheng Hao, a cold and perfect senior who also fell into the Arabic department but changed his life against fate.
It is a campus love story, which tends to be more realistic, but 99% of the whole text is about campus life, so it will still be sweet, relaxed and enjoyable. One final stab.
Concept: Campus is sweet, society is bitter, persistence is hard
