On November 4, Kohto Wakai, guitarist of the three-member band group Mrs. GREEN APPLE, was reportedly in love with NINA, a member of the nine-member girl group NiziU. Nina of NiziU and Mrs. Wakai collaborated on a video and had a “flirting scene.” In March 2025, “FRIDAY Digital” reported that Wakai was in a relationship with gravure idol Miri Kazuka. It has been pointed out that they may have been dating at the same time, and “two-timing” allegations have erupted on the Internet. Sony Music Labels, which manages NiziU, responded to the news by saying, “It is true that we recently became friends through playing guitar. It is a relationship of mutual respect between senior and junior members. On the other hand, Mr. Wakai’s agency said, ‘There were some items that were not true, but we basically leave his private life to him. Wakai is the core member of Mrs., and she is also a member of the band “Phase 2,” which is the activity category of the band. The band has just announced that it will end “Phase 2,” its activity category, and move into a new “Phase 3” on January 1. In addition, she has become a representative of the music industry, appearing on such endowed programs as “TV x Mrs.” (TBS) and garnering attention for her collaborations with Disney. Meanwhile, NINA became a member of NiziU in 2020 after passing the Nizi Project, a Japan-Korea joint audition program by Sony Music and Korea’s JYP Entertainment. The group made its pre-debut in 2020 with the digital mini-album “Make you happy” and has since released a series of hit songs, including “Step and a step,” which was released in 2022. NiziU’s agency, JYP Entertainment, bans romance for three years after debut, but now five years have passed since her debut, and romance itself is a free state. However, if he had been in a relationship with another woman at the same time, NINA would have been heartbroken. Also, since Mrs. Omori Motoki, a member of Mrs. Omori, produced NiziU’s song “AlwayS” in May 2025, there are some who are concerned about their relationship. In October 2025, “Bunshun Online” reported on the two-timing of Ai Takahashi, a volleyball player, and Shosei Ohira, a JO1 player. This is especially damaging for artists and idols who sell their “sincerity. As you can see from the reaction to this incident, many people are still a little disappointed.
