Miyawaki Sakura (LE SSERAFIM, ex. HKT48, IZ*ONE) - Sakura really liked Chichi's work and vice versa, they met through Changbin who knows Chaeyeon (soloist, ex. IZ*ONE, JYP trainee). Since then, they spend a lot of time together (as much as their busy schedules allow). They often play console games and watch dramas together while expanding their Korean vocabulary. Chichi also confessed that she had watched Sakura on stage since HKT48.
Komiyama Haruka (AKB48) - The girls met not long after Haruka confessed in an interview that Chichi was her ideal type. Both are big fans of the "Love Live!" series.
Ushio Sarina (HINATAZAKA46) - The girls met after one of Stray Kids concerts in Japan where Sarina attended. Chichi quickly "fell in love" with her gentle personality, and they have exchanged letters frequently since then, which they both find very cute and more personal. As part of promoting Stray Kids with "Circus", Chichi received a 15-minute segment on Japanese radio, "I Can Say It!", with Sarina as co-host. The program was broadcast twice a week for 2 weeks (4 episodes). During the show, there were many cute interactions between them, which ultimately stole the hearts of fans.
Myoui Mina (TWICE) - The girls obviously know each other from the label. Both are trained in ballet, sometimes spending their free time recalling some choreography. In addition, they often bring each other gifts from Japan whenever one of them is there. Both Mina and Chichi have mentioned multiple times on Bubble that they are currently together - they both always send then a short text message: "🐧🤝🐯".
Changbin, Hyunjin & Jeongin ➡️ ♡♡♡
Song Mingi (ATEEZ) - They became friends during Guerilla choreo making period, where they quickly became the loudest duo, mainly due to their loud laughs. They also often teased each other, to the point that most of their conversations, taken out of context, would have indicated that they hate each other - which only shows how similar their sense of humor is.
Choi San (ATEEZ) - San was the first one to approach Chichi during Kingdom. He then complimented her amazing dancing skills and unimaginable condition. Achieving something similar, he stated, was his goal. Chichi was very touched by his words, and after the show, away from the cameras, they quickly became inseparable. The two often train together. Chichi on one of her vlives confessed that she and San often like to tweak existing choreographies by making them more difficult. They like to feel tired and see how far they can push their limits.
