I really like all the girls. Especially the sweet and tender Alyssa.
Although I am a person who prefers older women. Having two incredibly sexy, beautiful and attractive older women as Susan and Lily are, I'm satisfied with this.
However, so far, it's kind of hard to "empathize" with both of them. I mean, they both hide something regarding the MC's past, so it won't be so easy to trust them and the reasons why they hide things. Contrary to what happens with Chloe or Alyssa, for example. Who, at least for now, don't seem to be related to the MC's past and I think they are relatively easier to empathize with.
I understand that maybe they don't have enough trust with the MC to reveal the whole story, but I'm not buying the typical "I did it to protect you". It's clear that eventually they will both have valid reasons and they definitely won't be the villains of the story. On the contrary, I think they can help a lot and collaborate with the MC to solve the mysteries of their past.
So I hope soon we can start romancing Susan and that her possible romantic relationship with the MC will not be hindered or stalled too much because of all of the above. I am convinced that Susan is a good person and deserves to be loved by the MC. I have a lot of faith in Susan's romantic route.
