Background and release
On October 6, 2009, it was announced that Arashi would be singing the opening theme song for the television drama My Girl, which stars member Masaki Aiba. It was released in two formats: a regular and limited edition. Included in the regular edition was the title track and two B-sides, "Tokei Jikake no Umbrella" (時計じかけのアンブレラ) and "Super Fresh" (スーパーフレッシュ). Instrumentals for all three tracks were also included. The limited edition included "My Girl" and "Tokei Jikake no Umbrella" and came packaged with a DVD, which contains the promotional video for "My Girl" and the making-of the promotional video. The b-side "Tokei Jikake no Umbrella" was used as the theme song for the mini drama 0 Gōshitsu no Kyaku (0号室の客), which stars various talents from Johnny & Associates.

Music video
Shot by Yasuyuki Yamaguchi (山口 保幸) in a drama-like setting, the music video opens up to the front of the Maiga (舞駕) family household and Saburō (三郎) (Masaki Aiba) removing the family nameplate from its place next to the front door while the bickering of his brothers can be heard from the inside.

At the dining table, Jirō (二郎) (Sho Sakurai) and Gorō (五郎) (Jun Matsumoto) are looking at a floor plan. Jirō writes his name in the space of the biggest room, but Gorō crosses Jirō's name out and puts his name instead. They continue to fight for the room until Shirō (四郎) (Kazunari Ninomiya) takes the marker from them and writes his name in the space of the smallest room, puzzling the both of them.

While everyone else continues to pack, Ichirō (一郎) (Satoshi Ohno) picks up a picture frame with their mother's photo and carefully puts it into a box. Saburō looks through a photo album and finds a letter from their mother addressed to her sons at the very back, saying that she will be watching over them from the house no matter where they go in the future. He shows the letter to his brothers; Ichirō then takes the floor plan and rips it up.

The scene shifts from a living room full of boxes to a clean living room with everything back in its place. Gorō sends text message to their father, telling him that they will not be moving out of the house in order to stay with their mother. Shirō puts the picture frame of their mother back, and Saburō reattaches the family nameplate, now including the name Hanako (花子) next to theirs.
