In skzflix only leeknow had the scar on his face which indicates he traveled to a different universe. in every universe there is always two parallel worlds which means there will always be an original and a clone. skzflix is the parallel world to the mix tape: oh universe. In mixtape oh leeknow surivived the crash but there club disbanded. while in the skzflix leeknow was brought into the universe were he and his club was still together. but since there is a version of leeknow that harms versions of skz it took time for the original felix to trust him when he woke up. in the crash leeknow lost most of his memory but throughout the mv he gains it back. felix then leaves him to go back to his world. when felix travels in the multiverse he jumps in and randomly out universes without control. thats why he knew who leeknow was, both of them could travel the multiverse. but since felix was pushed off a building in ordinary it caused felix to unlock his multiverse powers and get lost in the multiverse. Felix only visted leeknow in skzflix to help him be a better version of himself which gave leeknow the opportunity to redeem himself. but in exchange felix would be non existent/ forgotten in that universe (thats why in the view felix is trying to find them).
in the end felix goes back to his world thinking its a dream because when he dreams he gets to see his members even tho hes forgotten. but leeknow in the skzflix is stuck knowing a version of felix.
Now after reading about skzflix the quote found in the mv "dreams come true to those who truly want them" has alot more meaning now
The scars on the two indicates they were both in a different universe
