先頭はすでに人がいっぱいで、ぼくらは後ろで見てたのでお母さんサーバルの存在に気づきませんでした。
ちなみに上からお肉ぶら下げてたのが噂のしんざきおにいさんだったようです。

The front of the area was filled up, so we were watching from the back, so we hadn't noticed the mother serval's presence.

I hear the person who dangled the meat from above was the rumored Shinzaki-oniichan, by the way.
