Yeah. Far too much crammed into 5 days, which makes a lot of the interpersonal developments seem "off". Especially since the timeline is supposed to speed up after the first basketball game. I mean, hell, they've already lived in 4 different residences so far in 5 days (not including the RV) and MC still needs to move.
It becomes odd in some of the dialogues, like Rainn mentioning MC not hanging around the diner lately. I mean, he first visited it ever on Day 3, visited again on Day 4 after hours (though she might not know that) and then she says it on Day 5. Just an odd line when you are aware of the timeline (easier for me, perhaps, since I first played on Day 5).
"Coach Harper isn't the problem", are you sure? You literally met her the day before, and have never experienced her coaching. At best he should have been on "I want to give her a chance" as opposed to "If she goes I go". If they had, had some time to do practices before that scene, it would make more *sense* but it feels disingenuous in the current scenario.
