"Please read"? You clearly said, you got 11/14 on the final day. So you already failed 2 days. Taking your own risk by doing that. And then the calendar tells if you get the girl IF you complete thoise missions in the same day. Not a day later, specially after the event.
As for going back to my "reading" I read it perfectly, as for your intepretation, it has much work to do. Visuals are Visuals. I have 14 event missions on "claim" and the calendar says I cannot obtain her, I can still claim all thoise 14 missions and obtain the girl. This has to be within the event timer. Like every normal person would understand
