Hi friend! Either way, MC does get kicked off the team, it's inevitable😅 that said, if you're trying to make team captain by the semester end, that's very possible! You basically need to pick choices that involve the team, weightlifting, or being a team player.
I didn't create a guide for this game, but if it's something you're interested in, lmk! There aren't really "bad" ends in this game, and your grades/captain status/ who you date or don't influence dialogue and events in the sequel as well 👀
