"Summer Song" is the twelfth single by Japanese pop singer-songwriter Yui.

[1] The music video begins with Yui playing guitar on a wooden platform and on a grassy field, and a girl making a picture frame with her hands and capturing various scenes of summer.

After drawing pool-cleaning duties along with a boy, they spray water at each other and run around the drained pool.

In the middle of the video, the girl is shown holding two tickets to a fireworks festival, and quickly putting them away when the boy looks at her.

At the end of the video, the girl manages to gather her courage and ask the boy to come with her, which he gratefully accepts.
