I'm theorizing he also time traveled like FMC, but came from FURTHER ON when he discovered what was going on. If true then he is an idiot to not figure out that her change of behavior and pushing Zera on him indicated SHE WAS ALSO FROM THE FUTURE! Instead we have this stupid of him wanting to "protect her this time" mixed with her fully believing the deception that he could have cleared up but decided for "FMC own good" to keep a secret! (God I hate that trope, "Oh Ho I'll protect my loved one who died because of misinformation....by CONTINUING to let her be misinformed!" Seriously this is why I LOVE when the STBX gets made a second ML or the loser still clinging to the woman he was already ready to throw away and did in the old timeline annoyingly instead of "getting the fucking picture!" God I want to see this type of story result in the ML losing anyway one day! I'm hating "Do-Over" stories with Time Travel! Can we get a "do-over" where there is no time travel and the idiots have to REPAIR their broken relationship like NORMAL FOLK DO or move the fuck on!)
