Maya, because she needs the MCs help to pay for college. Hell, she might even have to choose between the MC and Josy if it came down to brass tacks.
Maya still doesn't know if she likes boys, it would be an achievement of a certain level. and also the problems she has to face don't make it easier, but much more complicated.
Josy continues to be the right girl at the wrong time:
1) in the first chapter they finally talk to each other, but MC has to leave for college "goodbye Maya I have to go"
2) in the second chapter after their first real date it is Josy who is convinced that she will never see Mc again "goodbye MC, unfortunately I will never go to college".
3) in the third chapter all the unsaid things emerge and technically only because Derek has fixed MC at Maya's place they don't meet again, an event that probably would have changed the story "goodbye Josy, you lied to me".
4) in the fourth chapter they say goodbye for the fourth time or they embark on an adventure that in reality I would never call easy.
