i don't think there is a way to be out of her route, especially so early in the game. I cannot remember well, maybe you need some more frienship points before being able to gift her. Try again next days.. What do you mean "the only one that doesn't have that"?I know but shes the only one that doesnt have that?
Am I locked out of her route?
Truth is that I still haven't completelly understood how the "week period" counts, for some times i gift them every few 4-5 days.
Some girls you cannot gift, such Vinvent's girlfriend, which you can get f.p. but she will not accept gifts.
Before you ask, i tell you that you won;t be able to flirt Evelyn for a looong time ( i have 3-4 hearts and still can't).
