Photos related to NewJeans member Hyein's birthday were released on the official account. At midnight on the 21st, the NewJeans official account posted multiple photos of Hyein along with the message "HAPPY HYEIN DAY." This is the first time in about six months since last October that member photos have been uploaded on the official account.

Hyein showed a pure yet mature atmosphere with long straight hair, simple makeup, and casual styling. Photos of her wearing overalls and a T-shirt were also revealed.

No new videos have been uploaded to NewJeans's official YouTube channel since last Christmas. However, with the posting of photos related to Hyein on the official account, some fans showed interest in the possibility of resuming activities.

No separate news about Hyein's birthday was delivered on the fan communication platform Poning. NewJeans has been communicating with fans through Poning since November 2022, but recently the members have stopped communication by changing their profile pictures and phrases. On the other hand, a popup message celebrating Hyein's birthday was provided on Weverse.

After the exclusive contract dispute between NewJeans and Adore, Haerin and Hyein returned to the agency after discussions, and Hani also expressed her intention to return. Minji is still in discussions with Adore, and Daniel received a notice of contract termination. Adore filed a lawsuit against Daniel for breach of contract and damages amounting to approximately 43 billion KRW.

In mid-April, it was revealed that Haerin, Hyein, and Hani visited Copenhagen, Denmark, together with Adore staff. They were spotted moving with filming equipment on site, and Adore stated, "NewJeans members visited Copenhagen, Denmark, together with staff."
