Xu Jin's impression of the Zhenhai Team was initially influenced by societal rumors calling them the "Harem Team."
Aside from the captain, the entire team was female, all young and beautiful girls, which made it hard not to let one's imagination run wild.
But speaking of solid proof, there really was none—especially considering that Yan Yu had remained single to this day, without being romantically linked to anyone, which seemed to prove he likely had no other intentions towards the girls on his team.
Thus, new rumors circulated that perhaps Yan Yu was actually into men, like the strange love triangle between him, Liu Longtao, and Li Zhaojiang... Now, through his own eyes, Xu Jin could clearly see there was nothing special between Yan Yu and Li Zhaojiang; he obviously had more interest in the deputy team leader, Li Minghu.
As for Li Zhaojiang, he was merely the toy they teased when things got ambiguous.
