There's a girl living in an apartment. That girl is so beautiful, she loves music. Like today, she plays classical songs using vinyl. Then she started dancing in her vintage dress. She danced to the accompaniment music, very pretty. Until she didn't realize that her apartment window was open. Anyone can see if she danced like a girl in the '90s. Meanwhile, across from the other apartment building, Asahi keeps looking at the girl with a little smile on his lips
