I'm just speculating, but... He didn't know Zaihang was alive until recently. He definitely liked Zaihang back then, but when he thought Z died, he went on with his life and found another admirable person, Jing. Who wouldn't admire Jing tho? Everyone in this universe knows who Jing is.
I'm so curious as to why Renzou is such a big fan of Jing (like to the point of wanting Jing to fuck him LOL) when Zanghai was the one he bonded with.... Any spoilers?
