That's a really indifferent way of breaking up with someone.
In other news, it seems Chihaya is still struggling to overcome her much mentioned weakness, related to multi-syllabic cards, and Taichi is determinedly clawing himself up, so he can finally compete at Arata's level (also, reaffirming that his family is indeed a wealthy one).
Another thing of note is that Taichi still seems to be as hesitant as ever in acting on his feelings towards Chihaya. I wonder if he feels that he has to beat Arata in Karuta before he feels worthy of Chihaya's affection (rampant speculation ahoy!).
But importantly, I'm glad that Tsukue-kun finally managed to stand out as a club member. As realistic as it is, his tendency for self-pity was getting a little irritating, so yeah. It's good he finally has something unique that he can contribute to the team.
