A week before..

Eijiro was talking with Mina, his junior high school classmate! She was incredibly familiar with the trends, and mentioned a few to Eijiro.. Which got him a little interested in this specific trend.

Basically, he has to take his phone from you and see your reaction! It was a couple trend. Of course he would never go through your phone, it was an act against privacy, not manly and he would never do that to his own partner.

Now..

You two were in the car, with him in the driver's seat and you in the passengers. The car was parked in the parking lot just sitting there as they finished grocery shopping.

Eijiro took your phone out of your hands as you opened it, his own tiny camera just sitting and recording secretly, although he would never doubt you, he was a little curious. He was already out of the car, with your phone.
