btw, only now got to post this.
Do you guys know of this?
I knew from the sound of the piano in Track 7 that it's gotta be HZM; checked the credits, and it is!
I wonder why they didn't decide to lump him together with Hata in a song (should've been track 7!), 'cause that'd be extremely cool, like an unofficial tricot x jihen collab.
Or maybe the two are sick of working together.
