Is Lily really considered side girl? My first route was with her and i dont bother with other girls much especially after ep9.
Sidegirls are Sidegirls, and it will stay that way, this episode made it clear for everyone... There isnt even something major with Quinn and MC.
Lily got some content in this episode, Rio, Quinn, Nicole barely anything. Yeah you can kinda "date" Lily now, or roll with her... whatever... but in comparsion to the maingirls, its nothing. Same goes for every other girl in the game besides Jill, J&M, Bella and Sage. And even the last guy now have to see that.
Some of the sidegirls got a little "promoted" during the game, Quinn, Lily, Nicole (Envy) and Rio are those girls that standout of the sidegirls... but still, they are sidegirls and that will not really change until the very End.
If you ask me, Season 3 will kinda be "the end" of the game like we know it now. DPC already said it himself that season 4 will feel very different as the other 3 seasons. So maybe during season 4 it will be possible to really build a ongoing relationship with some of the sidegirls. But for sure not that heavy like with the maingirls. Jill in episode 11 got more content than Lily in the entire game.
