In the ABO world, compatibility is the criterion for testing true love, and people with high compatibility are destined to be together. This is the idea that the world has always instilled in Xia Heding. Xia Heding is a lucky alpha because he has a highly matched childhood sweetheart, Shen Zhijiang. Xia Heding always thought that she liked him and even regarded him as a future partner. It wasn't until he was divided into classes again in his second year of high school that he saw the person who had been ridiculed as his love rival, Lin Wen. Lin Wen also liked Shen Zhijiang, at least according to gossip. Moreover, his and Lin Wen's pheromones were so conflicting that they felt uncomfortable every time they got a little closer. Xia Heding always thought that the two of them would not have any intersection, until something unexpected happened. Lin Wen took the first step to show his goodwill towards him, and he fell headlong into these affectionate eyes. When true love comes, the attachment between pheromones also becomes a foil
Concept: Pheromones are not the standard for testing feelings
