That last line was cheesy! "I think that if I return to her again, like a true man... Then Miyazawa will like me even more.", it was cheesy enough, but when you consider that he is saying this because he is going to go to a kendo competition in Tokyo and be gone for a few weeks, it just is embarrassing it is so cheesy.
Anyways, wonder what love rival is going to appear while Arima is gone (or perhaps it will be a new girl vying for Arima). I just have a feeling that this is going to happen, although since I hate love rivals usually I am praying that it isn't, or if it is that it is well done.
