Boss plays a little boy who falls in love with his brother's girlfriend in the first love song micro-movie. Anting plays the girlfriend. At first, Anting sits on the bus and recalls the days when she got along with Boss, and then she leaves. She sends a text message to two people, one is Boss's brother and the other is Boss, and then only Boss goes to an appointment. It happens to be Anting's birthday, and she doesn't want to be alone. Then Boss sings to her. That's about it. I hope it will be adopted. Thank you.
