Dmitry Shamovich and his wife Anastasia Kuzmenkova play with the dog Amur at their homestead Zaimka Leshego in the village of Sosnovy Bor, Belarus, February 7, 2018. "Four years ago I was here, at the homestead for the first time - we arrived with other birdwatchers to build artificial nests for owls. And I met Dmitry, the owner of homestead, for the first time, here. Later we met again, when I arrived to be a volunteer in a project related to capercaillie. After that we made more projects together and one day I understood I fell in love with him. It was mutual," said Anastasia. REUTERS/Vasily Fedosenko SEARCH "GLOBAL LOVE" FOR THIS STORY.
