This is Russia (Ivan Braginsky) from the Hetalia Axis Powers anime and manga series by Hidekaz Himaruya. The background pic looks pretty simple but that just makes the main focus of the photo really stand out
"The Love of Sunflowers." I'm a huge Ivan fan, and it's weird, but I see sunflowers somewhere literally every day. So a friend of mine and I have a running joke where Ivan (or the unnamed "my Russian man") is sending me sunflowers every day.
