No, he didn't remember that he slept with Josh back then, he just remembered him as bodyguard who reassembles the person he slept with and there are few lines he says to Josh before the coyotes attack like " You had a good looks for a bodyguard , so I remember your face" Something similar like this but I didn't remember exact words.
Spoiler if you want : he won't found out Josh is the one he slept till the end, so we didn't need to waiting for him to find out, tbh he is just too naive for that!!!!
How did he find it out btw
Ohh that, well Josh will reveal that himself after they fall in love, he will try few time to say it but didn't get the chance, after there will be one incident, it's kindah touching so i didn't wanna spoil that Movement, so Josh will reveal it then, Chase won't find out himself
Side note : he won't find out even after seeing Pitt, because in novel it mentioned so many people find Pitt looks a lot like Josh then a chase, idk why he looks like Chase to me too
The ml remembered the mc? Since when? Or did I missed it
