Weird faces may be an asian thing. Show Luo was also like that in his pics with Kuu

Talking about him btw I think they should collab again, they're always re-performing Twinkle lol
And yes, I'm a collab-need guy. She should make a collab album with 12 new tracks. With Show Luo, Clench & Blistah, Maki Goto, Kana Nishino, BACK-ON, Aya Kamiki and more
