Fed up with being envious of the lovebirds he kept running into in cafes, Keisuki Jinushi started a blog teaching single readers to take brilliant pictures with imaginary girlfriends, like these.
Scroll through to see the lengths he goes to for his make-believe relationship.
Keisuki, 28, calls his photo series "hitori date" (one-man date). He became an Internet sensation earlier this year.
"My grandma said she burst into tears after reading my blog because her grandson seems pathetic in these photos," says Keusuki. "But (I'm not) ashamed of being single. You should be puffed up with pride and say 'Yes, I am on my own.' You should act like it's normal to be alone. Then the world will be slightly brighter."
"Most readers comment that it's 'interesting' or 'fun,'" Keisuki says about his fan base. "Although there are female readers leaving comments, none of them have said, 'Let me be your girlfriend.' What a grim world!"
Just like real PDA couples, Keisuki says the first rule for single travelers who want to take "hitori date" photos is "don't be shy."
"The most suitable place (for loners) would be Japan," says Keisuki. "Many Japanese couples are so shy so they only hold hands. The worst place for singles is France."
"Couples are kissing everywhere. It makes you feel so jealous and it's even more painful for you to be on your own," he says.
Here are some of his tips for taking one-man date travel photos.
A tripod is the hitori dater's reliable wingman.
Leaving hand cream and other accessories on the table makes your fake girlfriend seem more real.
Apply a paler foundation on your right hand and bright nail polish on your nails, says Keisuki. Girly accessories like a puffy hairband on the wrist enhance the illusion.
