I'm just unable to figure out how liking the MC would affect her schedule that day, the game doesn't give any reasons...
Usually it makes sense, for example, we see Valeria at the beach when we go there with Alexis, Erynn, Iris... that's because Darryl and Tori invited her and she accepted, simple enough, cool.
In this occasion there isn't much reason why she's there or not, same thing for John.
"Valeria went for a walk midtown because she likes MC", isn't a sentence that makes much sense.
And John being midtown or not depending on wether Valeria likes us makes even less sense.
