Well, this is my first comment on MAL and I never imagined I would ever comment in a poll discussion, hell even cast a vote myself.
But I definitely want to see the Taichi & Chihaya together.
I just finished the 2nd season and the very dailog "..I'll always love Arata" has become my nightmare but it does make the anime all the more interesting. Just playing karuta matches one after another makes it look very dry.
P.S. No hard feelings for Arata. I really like this character and everything but I can't see him care for Chihaya in the way that Taichi does. Chihaya might look up to Arata but she still has no profound feelings for Arata. It is Taichi who has helped her everytime.
