VS Shadow

Shadow is difficult. Last night I and Haruka tried to shadow a couple. To be precise, they haven't been a couple. We arranged Yakiniku dinner to make a man and a woman a couple last night. So, they were a future-couple.
After the dinner, we asked them to go to a bar for one more drink, but she told us that she would go home. That's why, we said Good-bye to her and him, then we left the place.
After five seconds, our shadow started.
She would really go home? He would really and disappointedly let her go home?
Making other passangers a barrier, we hided our existence and chased them.

They walked slowly to a station, then had arrived at the center exist of the station. And they had a conversation for a while there. I and Haruka looked at them carefully from the place where they couldn't look at us. The moment, I thougt this night hadn't finished yet.
At the next moment, history moved.
They started to walk to the city. It was clear that they had gotten another aim different from going home. We also started to walk silently, and shadowed them.

They chose a narrow unpopular street as their walking route. It made us difficult to chase them, because we couldn't hide us among many unknown people. If they had checked their back side just once, perhaps we couldn't succesfuly shadow them. But, fortunately, they were very busy to think about theirselves. They couldn't realise they were shadowed.

I thought they would go to a bar or Karaoke. But, they walked to Denny's, a family restaurant. If they were high school students, I wouldn't complain of thier choice. But they are adult. So, I couldn't understand their intension. In addition, they stopped again in front of Denny's. And, after a few minutes' conversation, thet began to turn back to the station! What were you doing?

"The back I want to kick" is a million seller novel's title in Japan a few years ago. I remenbered the title when walking to the station "togeter with them".
Soon after the finish of the incomplete night, we sent a complaint e-mail to her. She is now scared to us.

I heard that they will meet again next weekend. I hope they can find us then.
