Ad Mare (Latin, "To The Sea")[1] is the debut single album by South Korean girl group Nmixx.

On July 9, 2021, JYP Entertainment announced it would be debuting a new girl group in February 2022, the first since Itzy in 2019.

[8] The lead single "O.O" was described as a song with "mixture of baile funk and teen pop rock" genres with "intense captivating trap intro".

[9] Tanu I. Raj from NME gave Ad Mare 2 out of 5 stars, calling it "inconsistent" and "choppy" due to the uneven transitions from electropop to pop rock to hip hop in "O.O" Although he appreciated the simpler melodies in "Tank", he concluded that the latter was not able "to alleviate the damage that 'O.O' does".

[12] On February 18, 2022, JYP Entertainment announced that the group debut showcase would be postponed to March 1 after member Bae was diagnosed with COVID-19.
