Most basic plot and if it's it follows this way it meant , seme's bro definitely sending many people like uke to seme but he knew none of them are uke , till the real one(uke) shows up and may be seme and bro both scheming uke to stay by seme side in the name of saving his father who mighy actually not be injured but free later will betray or sold off uke. Also bro and seme scheming in company as well.
yep yep!
okay so i have a theory (which is kinda basic tbh)
the scar and the limp that the uke has are probably from some accident he had when he was a kid/teen. And he may have gotten it while trying to save the seme (bc the seme carresses and kisses the scar) who he either knew as a childhood friend who vanished shortly after (like min siwon's backstory in at the end of the road) or just stumbled across (I have a hunch it's the first option coz seme said "I missed you" and also shows signs of knowing him). seme lowkey feels betrayed by uke bc he expects uke to remain constant to the person he remembered him to be (the hurt look in the first bathroom scene) and bitterly accepts the position of being the scum who uses him and gets used by him bc it's the only reason why he thinks anyone ever sticks around him. seme also really likes -
maybe even loves - the uke (he was getting off on sniffing the pants the uke came on in the second bathroom scene)
