So I heard a song of skz called Christmas eveL the theme is about Christmas. They all play Santa role. And when they sing title it sounds like Christmas evil. And there is a line which is famous " felixz navida felixz navida I can see evil coming but felixz never bad " and this line also " jingle jingle jingle all the way my head is spinning round round bingo" either they are mocking or talking about a whole different Christmas. And in their concert i saw in fan clips green lighting is more the lights gave me bad vibes and Chan behaviour also as if he is high all time
