RiSENNE and Yaho~

In the Korean comments

One comment supplies a personal connection between the groups: in translation, “It’s cute that Minami took up knitting after watching Sakura knit.”

What the words mean

야호 (yaho, “yahoo!”) is literally an excited shout. Here it is playful catchphrase material: one comment groups it with 도도독 (dododok) and 오이쉬 (oiswi) as “the best catchphrases.”
