Okada Nana/Naachan talking about Sakura on her new Interview . Naachan: I appeared in lot of music shows with sakuchan, it seems that she’s having hard time lately. She has to go back and forth between Korea and Japan for PRODUCE48’s filming. She cried a lot in that show, but she normally not a girl who cries a lot. through her hard work alone, she can goes international as IZ*ONE member. It’s also amazing how she can decide to working overseas for 2 and half year. Not only sakuchan, hiichan & Nakochan, I think that all member who involved in PRODUCE48 is really brave .
