In 2020, sodagreen announced their comeback and released their new single Tomorrow will be fine. The six members also formed a new group Oaeen (literally "fish-nail-spool"), whose three characters are ideographic subparts of the characters in the original name Sodagreen. The Anglicization, "Oaeen," was a linguistically similar pun, made from the endings of the three syllables in "So-da-green". This name change was due to a name trademark dispute with former producer.

In 2022, Oaeen released a re-recording of their first album sodagreen, titled Oaeen . This record included all tracks from sodagreen, as well as new cover songs, such as Pretty Thing by Charlotte Martin, and That I Would Be Good by Alanis Morissette. On 1 October 2022, the trademark on the sodagreen name was bought over by sodagreen, with a validity of 10 years. In a February 2023 concert, the band officially announced the return of Sodagreen as the band name and their 20th anniversary events starting from 2024.
