Heron is Miro and Masha's father. When they were young, Mona and him had a summer love adventure. By the end of the summer, Mona was pregnant. She did not tell Heron at first, he discovered he was a father when the twins were about 7 y/o. After that, Heron has always been around and has always cared for Mona and the kids, even when Mona married Leila! #shallowfamily
