How do you complete the last part on Amelie on Day 0?? And the second part of Lily’s Day 21??
Check the girls status after school above your status, you can see what choices you made that could have been wrong for the ending. Amelie I think you have to reboot a few times until MC does things different and his stats are higher and Lily after the bus choose the drunk at a party option is where you might have made a mistake
