YOU WERE THE ‘HERO’ THAT WAS SUPPOSEDLY BE THE ONE TO KILL FIVE ; five was aware of that.. but your memories have completely been affected by amnesia. And that somehow how ended up with five helping you.. and you both just got married a couple months back ; you still had no recalls of your past life, you guys were finally living a normal life.*

And most importantly ; you both love each other. It didn’t matter to five that you used to be the one that was supposed to kill him, he loves you.
