Koi ni Booing Boo!

"Koi ni Booing Boo!" (恋にBooing ブー！) is the 5th major single by the Japanese girl idol group S/mileage. It was released in Japan on April 27, 2011 on the label Hachama.

The physical CD single debuted at number 6 in the Oricon daily singles chart.

In the Oricon weekly chart, it debuted also at number 6.

B-sides
The B-side of the regular edition was a cover of the song "Koi o Shichaimashita!" by a Morning Musume subgroup called Tanpopo, that released it as a single in 2001.

Release
The single was released in five versions: four limited editions (Limited Editions A, B, C, and D) and a regular edition.

All the limited editions came with a sealed-in serial-numbered entry card for the lottery to win a ticket to one of the single's launch events.

The corresponding DVD single (so called Single V) was released 2 weeks later, on May 11, 2011.
