Runrun's hair isn't even that short... it's already at/past her shoulders and she debuted with even longer hair. Weird to be so fixated on hair length. Japanese people don't blink an eye at women with short hair but everywhere else it's such a hoopla or too boyish. 3 of the other 2kis have shorter hair than her at this point... Risa too? But nah, you have to nitpick at the center. Hikaru was the most popular 2ki by far but instead we get conspiracies that she was chosen because of her hair length.
