Heize has just released the official music video for her song “Happen,” which is the title song of her seventh mini-album of the same name, and to many fans’ delight, the music video stars South Korean superstar actor – Song Joong Ki. The track is about meeting someone who makes you question whether you’re meant to come across them in life.
