Ayaka and Miura Daichi will release a collaboration single titled "Heart Up" next Valentine's Day, February 14.

"Heart Up" was written and composed by Ayaka, while Kobayashi Takeshi arranged and produced the song. In February, there were plans to produce a tie-up song for a certain CM. That's when Ayaka and Miura, both born in 1987 with close debut dates, came on board with the plan. The two along with Kobayashi started meeting up in summer and finished the song shortly after participating in KREVA's event '908 FESTIVAL 2017' in September. 

The single will be released in a CD+DVD Edition and a CD-Only Edition. Both types will include the song sung by Ayaka and Miura alone. Furthermore, the DVD will contain its music video.
