Su Yinan's Niche Preferences

Song Nuan never expected that someone would surpass him after he had been ranked first in his grade for two years! I heard that she was still a transfer student. From that day on, she secretly vowed to regain the first place, so she started all kinds of overt and covert fights with Su Yinan. Since Su Yinan transferred here, Song Nuan has never won first place again. Until Valentine's Day in my senior year of high school Friend Su Yinan suddenly asked Song Nuan: "Do you know the word niche preference?" Song Nuan: "Is it something that a few people like?" Su Yinan looked at Song Nuan seriously and said word by word: "It's me who likes you. The wind in Haicheng doesn't know, the sea doesn't know, only my heart knows it clearly." It seems that from that time on, the classmates in the class noticed that the atmosphere between the two enemies was different. It wasn't until the day of the graduation party, when Su Yinan forcibly kissed Song Nuan in front of the whole class, that everyone realized that the two bosses were studying openly but secretly falling in love. This is a story mixed with youthful love and growth and healing. Most of the plot and even character prototypes in the story come from the friends I had during my youth. This is my first time writing, please give me some advice.
