If you liked Toradora, you should check out the newer series Golden Time which was originally created by Yuyuko Takemiya, the same person who wrote Toradora. So far the series is pretty interesting as a drama.

Banri Tada is a newly admitted student at a private law school in Tokyo. Due to the after-effects of an accidental fall from a bridge shortly after high school graduation, he lost all his memories from before then. At the time of the accident, Banri's soul had escaped from his body, and the "Spirit of Banri Tada" came into being, carrying his memories from before his mishap.
