 If you liked Toki wo Kakeru Shoujo |  ...then you might like Monogatari Series: Second Season |
The art between these two anime series are extremly similar and while only one arc, but this movie have the same concept " time travling for good reasons always gets back at you ". The romance is a supporting role which is pretty well done.

"Kabukimonogatari" and "Toki wo Kakeru Shoujo" are both about time travelling. Koyomi saved Mayoi with Shinobu's help but transformed the future world; Makoto used her ability of time travelling to change some trifles but hurt her friends. We can see the butterfly effect brought by time travelling in the two anime.
