"Only You" is the second single to feature the four 9th generation members.[3] The single was released in four versions: a regular edition (catalog number EPCE-5785), and limited editions A, B and C that include a bonus DVD; each edition also sports a different cover.[2][4] The first press of all editions came with a serial number card, which can be used to enter a draw for tickets to the single's release event.[2] The Single V was released 2 weeks later on June 29.[5] Certain retailers which sold the single, including HMV and Tower Records, also offered a B3 poster to customers who purchased the CD at their shop.[6]
The single was originally due to be released on May 18; however, due to the effects of the earthquake and tsunami, the release was delayed.[7]
The music video was released on the group's official YouTube channel on May 23.[8]
