it's not on melon, bugs, vibe. only on flo and genie, it's so weird, I don't understand how IU topping all chart couldn't do it and he did it with two charts and not even on no.1? is it fandom factor?? but how?
Mass downloading, no one pays attention to this stuff. Lim Youngwoong fans, Shawols, Arohas, and Fuses (ONF fans) do it too
