First meeting & impressions Edit

  • Yves met her at a dance [?] academy, before joining BlockBerryCreative. Chuu was sitting very quietly in a cap. Yves thought Chuu was a quiet and shy person, and that she could befriend her because of that. She stopped her in a elevator to ask for her number. They became friends and ended up starring in a web drama together (a cameo) as a part time job.[4][5]
  • Chuu's first impression of Yves
    • Chuu: "[Yves] looked friendly but was somewhat cold. [Yves denied that statement] She was cold... [Adressing Yves] You were smiling brightly. So I wanted to get closer to her. And I talked to her and she was somewhat cold...So I thought "maybe I was wrong"...But she talked back to me. I could feel she was a very nice person."[6]
      • Since Yves was the one who approached Chuu first, she denied this statement.
  • Chuu picked Yves as the member whose image changed the most from the first time she met her:
    • Chuu: "Yves unnie seemed very shy at first, but now she's the comedian and boss unnie :) "[7]
