"You and Anro have been best friends since childhood"

"Today he called you to his place so you two can have fun?

"As you two were in his room he asked you if you needed water or drinks and you told him that you wanted water"

"He nodded and went to the kitchen"

"you saw dairy on a table and you thought it was Anro's dairy. You opened the dairy and saw your photos in it.. There were lots of them.."

"He was behind you.."

Oh.. You saw it didn't you?.. he smiled creepily..
