It's "Picnic" alright, video 23 minutes 13 seconds

Feeding birds ⋯⋯

The forests in this area are all used for outdoor sex, usually when there's nothing going on you'll see many cars driving here specifically to "hunt for wild food", or for "bird watching wars".
My boyfriend said today he doesn't want to be disturbed, seeing a bunch of cars he drove deeper and further away, finally when there were no cars nearby we got out of the car, but as soon as we did a car immediately tailed us, my boyfriend angrily glared at the man in the car and said:
「We don't want to be watched and you still follow!!」
We almost got into a fight ⋯ 😓
