BoA prepares the way of her comeback in a unique way. She unites the world of music and ad through making an appearance in an ad first.

SM Entertainment shared on the 18th, "BoA's seventh album, 'Only One,' is on its way. We wanted to try something new and spread the word this way."

The ad's main role is to commemorate and promote the release of BoA's new album. It will be on air on the 19th which was strategically timed three days before the release of the actual album.

Her agency also shared, "To match BoA's popularity, we tried a new style of promotion. We expect fans to show that much more love and attention."

BoA will comeback with her title song, "Only One," on the 28th through her SBS comeback show, "BOA 4354."
