Yeah, now that I remember she left soon after the Valentine's day, I don't know how are the school times in Japan, but here its on Febreaury and the graduation on December/November.
I feel sorry for Ryuji, he waited for over a year... That should really hurt, not even a call after those 2 sms, and when she came back all she did were to head-hit him
I still like the novel's final more, since they still got 1 more year to assist together to the school before starting to think about the future and those things, got a younger spirit
