The popularity of Japanese idols is fascinating.

‌Moreover, with RESCENE, their main hit catchphrases
are in Japanese, like "Yaho" and "Oishii."
It's truly fascinating.
Of course, since individual idols are highly likable
and speak Korean so well, that might make them even more appealing.
Perhaps that's why the Korean proficiency of Japanese idols
active in Korea is quite high across the board.
The syndrome of RESCENE's Japanese catchphrases is both fascinating and surprising.
