IIRC only Kings of defeated teams can join another team after losing for example Riser joining Ruval's team or Seekvaira who might join Sairaorg's team (but this is a rumour according to V25).

The way I see the relationship between Lint and Cao Cao is that of a student who looks up to their sensei's friend no romantic overtones (or undertones? unsure on which one is right).
