I think Valeria is that kind of girl that likes to have hot guys around trying their luck with her, she gives "just enough" to keep them around and make them think they have a shot with her but not enough to something actually happen between them, its "just" like a attention thing and to have "fun" (she always says something about having fun)...besides all the things she doesnt seem to be going out (kissing and stuff) with Daryl or any other dude aside from MC (my assumption). She kept Zach in the friendzone and probably just hang out with him because she didnt know anyone at the time, when she made her first friends she ditched him like you said, as he doenst fit the kind of guy she likes to hang out with. Daryl is thirsty for her and almost exploding, to the point of not caring about Tori. Dude from the gym is being treated like some gay friend probably, a convenient friend from the gym..if she was not caring about his hands on her ass she probably has him at the bay for a
looong time. And i think at first she had the same intention with MC, keep him around the same way the does with Daryl (the 2 hottest guys in school on her pov), but i think she started to like him more than she anticipated...in the gym we saw how she didnt give much attention to Daryl because she was talking with MC on the phone, and i think once she secures MC and start something more serious she will ditch Daryl like a piece of trash with no remorse....probably setting MC and him in collision route (drama).
And, i was the only one that thought it was a bit weird Val's mother saying MC was even better in person? Val and her mother doenst seem to have a high moral compass about taking men from other woman, so Val's mother can try to cuck her daughter
And like you im not gonna put her on the shitlist yet too.
