From Peach Kyoudai:

Haruyoshi is an extremely good-natured person who is too easy to be fooled by people. While searching for a job to pay for his grandfather’s medical expenses, a young man with a mysterious aura calls out to him at a park: Sora, who introduces him to a part-time job that’s almost too good to be true.
――But, it turned out to be an outrageous job where he has to live stream (pretend) sex with Sora?!

A silly love comedy between a good-natured ikemen and a beautiful artist with poor emotions!
