H1-KEY's Yel and Billlie's Tsuki are friends

Tsuki gets along with everybody.

So it had exactly the effect they intended. Even Tsuki’s hairstyle in the fancam that has gone viral is supposed to enhance the „doll look“. If I had to describe their concept for this comeback I’d probably say it’s supposed to be like a creepy surreal childhood nightmare. But yeah, that being said: You do you, either you like it or you don’t!
