okay so IN TRUTH rz yaoi has moved me to the point that all my old favorite ships like barely register anymore TT i went about 10 years without reading fic too so it's rly just OLD ASS SHIPS no one gaf anymore and then basically all rz ships now....anyways:
1) HEETON/TONDDO YUPPPPPPPPPP
2) HEENEN/NENTTO YUPPPPP
3) kunten :3

(you didn't ask but) i thought about it and i think historically for me, my favorite ships were always whatever involved my bias, like i enjoyed qmi a lot and literally ate up any tao ship. with kunten their Story i find very enticing despite the lack of xiaojun...
