Practicing on the Stairs

In the Korean comments

The staircase setting appears to be a callback: one comment reads, in translation, “I hope this staircase series, which has continued since their debut, keeps going.” Another highlights what to listen for, saying Sohee and Anton have different vocal colors and that this makes their voices especially harmonious together.

What the words mean

화음 맛집 (hwaeum matjip, literally “a harmony restaurant”) does not refer to food. Here, it playfully praises RIIZE as a group that is reliably good at vocal harmonies.
