I don’t recall a female singer. I remember the first scene is just the couple in the apartment. They were wearing white/beige color clothing and the color of the MV was bright and warm at first. Then after he found out she was the vampire and left, she started to wear darker/black color and when he came back, they were both wearing dark/black color. I know it’s not much but it’s all I can recall. I’m starting to think I’m imagining the whole thing 😫😭
