NiziU members recently talked about their upcoming release of a new single in Korea after a hiatus of 1 year and 5 months. They shared their thoughts during an interview with Ilgan Sports at the JYP Entertainment headquarters in Seoul. The group is set to make a Korean comeback on March 31st with their second Korean single titled "Love Line," which consists of two tracks, including the title song and "What If."

Mako described "Love Line" as a song that symbolizes being connected to a destined partner by a red thread, relating it to fate lines on a palm. The group expressed enthusiasm for the second track, "What If," with Maya praising its band bass sound and beautiful lyrics. Rima likened the song to music from a Japanese animation and enjoyed blending Japanese music influences with Korean elements for their comeback.

NiziU's plans for 2025 include a solo concert tour in Japan, starting in the latter part of the year and extending into early next year. They expressed eagerness to explore new places and connect with fans during the tour, hoping to introduce more people to NiziU's distinct style. The members also expressed a desire to visit Nina's hometown of Seattle in the U.S. and shared aspirations to perform a concert fully in Korean to engage more with their Korean fans.
