sure! I won't go into full details about it. (also do not come for me. i love flx. he's one of the reasons why I started listening to SKZ and I have a bbokari tattoo. Do not take this as weird anti-flx behavior. IT'S JUST A THEORY)

But the first theory, and this is simply based on how Flx reacts, but I'm pretty sure whatever they fought about, HE started it. Just, based off how he grabbed on to Chn. Like, his fingers are DIGGING into his skin, afraid of losing him.

This leads into a second theory, which one of my friends suggested to me and i think he was either A. considering leaving the group, or B. leaving during tour because of his back injury. (he was diagnosed in Feb 2022, and the tour started in April 2022) Chn got upset because well, one. he has said on many occassions that he's his soulmate and I also imagine having already lost a member before this, really weighed on Chn's mind and losing someone who he had such a special connection with, was probably incredibly scary and heartbreaking.

so yeah, that's why I think they fought.
