There was yet another long pause as Hayashi Sakura and Mori Ken refused to talk afterward as if each of them were sent on their own reverie.
This is bad, Sakura thought. Aside from the serious and formal matters, there is nothing much to talk about around Ken that she could come up with.
Before these feelings emerged and became stronger as they are now, it was as if Sakura could easily talk to Ken. For her, he was the very first person whom she felt relaxed conversing about anything that they could think of talking about under the sun.
And now as the season changes and her feelings grow even stronger, Sakura doesn't even know anymore how to approach Ken. It was easy for her to deal with these if the other person is a total stranger like her ex-boyfriend for example.
Things developed rather fast between them, part of it is probably because Ryuuji was the one who is so quick to take action as soon as possible because of their stupid bet.
