Tennis is my primary concern, Hirokaba-san. There is a lot of data I need to collect on the current contenders in the area.

I merely wanted to make my intent publicly known for those who aren't particularly familiar with what I do. Things could be misconstrued since I would be someone unknown watching their practice. I didn't want any kind of misunderstanding.

Most tennis players sadly know who I am... I didn't feel the need to warn them as they're already sadly well aware of my methods
