In this short scene, Song Juhan tells us that he and his friend, feng zheng, have been in love for a long time, but that their relationship is now like water and fire. The two of them used to get along well when they were kids, but when they grew up, they began to compete with each other, and they didn't want to accept defeat, which is why they've been together for so long. They used to be good friends, but now they're rivals, and no one wants to lose them. They've had a crush on each other for ten years, but they haven't been able to get over it. They tease each other about it, but it's clear that they don't really care about each other. They just want to get on with their lives.
