LOONA TV #31 is the thirty-first episode of LOONA TV.
Before departing for Japan, HeeJin vowed to "study hard" to learn Japanese. In Japan, she attempts to speak a little, but gives up. HeeJin goes on to eat ice cream alone while HyunJin is filming.
- HeeJin's sentence in Japanese is supposed to be 私は今日本にいます (watashi wa ima nihon ni imasu; Right now, I am in Japan). However, she makes a mistake by saying あります (arimasu; "to be" for inanimate objects) instead of います (imasu; "to be" for living things), causing her to get confused and give up.
