I'm impatiently awaiting episode 4 too! And I'm rooting for Kensuke.
Poor Kensuke had to witness the moment between Haruko and Shoji
so I wonder how he'll react toward that and whether it will compel him to take any action of his own. It's so blatantly clear that Haruko's almost always on his mind, and he has seen and perceives aspects of her that Shoji hasn't but so far, he's only been made out to be a rather ineffectual marketing manager who's better at people relations than in strategic business relations. Well, that said, don't Haruko and Kensuke complement each other completely?
(Some people were speculating a pairing of Kensuke and Miyuki by the scriptwriters. Nooooooooo way!!!)
From the trailer for the next episode, I think Haruko had no reaction (outwardly) towards Shoji and even danced with Ryuto to spite him when he came to look her up at Cantante because she curtly told him not to talk about love in office. As usual, the two of them never pass up on the chance to trade barbs with each other.
Shoji called Haruko a blackhole in ep3 and in ep4 I think he calls her a lamp post. Evil! Haha.
