Yeah if I was playing this through the Lens of the MC and not through who I like best. I think your top 3 makes the most sense. Tho I would argue Layla to me feels more like a crush that turns into something more and not anywhere close to the same level as Iris and Alexis to me personally. But playing Layla's path not sure if this is my bias against Layla speaking or not. I never felt the MC was super into Layal compared to other girls it feels more one sided where Layla is into him alot but the MC is more just respectful , friendly and interested cause he is guy after all. While with someone like Iris , Alexis it actually feels they are into each other equally same with a few others.
