ABO, double A, some original worldbuilding, school setting.
During the ninth-grade unified exams, Gu Suijing went into heat, and Jiang Zhunzhi stayed by his side, calming his out-of-control pheromones. From then on, Gu Suijing fell in love at first sight. He kept his feelings buried deep for a long time, until they met again in their second year of high school, only to discover that the other was an Alpha.
"It's okay, Zhizhi. You won't get away this time. Whether you're an Omega or not, I'll always be devoted to you."
The flutter of young love planted a seed in their hearts, one that finally sprang to life when they met again.
This is my lucky coin. Now I want to give it to you.
