@FrostedFoxes Sounds like you didn't play Sun and Moon, then, because Lillie's relationship with the MC could definitely be interpreted as having romantic undertones. (Especially because some of her reactions to things like Olivia's Z-pose were, as I recall, Kinda Gay.)
This is true of the female MC, anyway. I didn't play with a male character, so I can't comment in regards to that.
@WhoCares Ah yeah I haven't played a pokemon game since diamond & pearl, or the old pokemon mystery dungeon game, I thought this was just some random fanfic.
