is that ending 3? or it's another ending?
Ending three is just kissing Casper, marrying him is a secret ending (ending 5)!(im trying to get it, you have to make very special and precise choices i think, or just get the third, kissing ending, and redo everything and an answer with a marrying (as a joke) topic will appear on day 5 or 6 before he confesses, i still haven't got the ending but if i manage to get it i'll update you about it :3)
