>>89005111Sandy has a lot more character than Amaya.
To start, outwardly Sandy is a sweet type who believes being nice to others and talking things out, that kind of stuff. She also seems to be kind of spacey and forgetful, going by the fact that she forgot everyone from elementary school except Mike and the unintentionally hurtful way she greeted Daisy.
Sandy's issue is basically that she was forced to grow up too fast thanks to her mother pushing her into modeling. It caused her to never have time for normal life, and that chapter focusing on her a long time ago showed how frustrating it was for her.
Model Girlfriend shows that as Sandy has gotten more successful as a model she found a new way to cope with it. Sandy gets a real satisfaction from doing a good job at something, and that's how she learned to enjoy modelling. However, Sandy seems to really dislike things doing things she isn't good at, note how she had fun at the video games as long as Mike let her win and got mopey as soon as she realized she was shit. She also has mentioned several times about how smart Mike is compared to her.
Also, she took a sour grapes type of attitude to all the "kid" things she couldn't do anymore because of her career. She tells herself it's fine she can't do any of those things because they're immature, and she's more mature than that because of her big adult career. As much as she tells herself that, having so much responsibility and so little free time clearly puts a lot more stress on her than she wants to admit and she causes her to act out.
Not to mention her random breakdown in Mike's room implies there's at least a bit more we still don't know yet.
So yeah, a lot more character than Amaya. Done with my Sandy analysis now.
