Edwin/Charles — Shared amnesia curse
At some point earlier in their partnership, Charles and Edwin accepted a case involving a powerful magic user they ultimately defeated and sent to Hell. They'd been slowly falling in love for years by then, and finally got together.
The magic user noticed, and just before Hell grabbed them, they cursed Charles and Edwin to forget they ever fell in love, and to forget every time they fall in love. Every year or two, Charles & Edwin realize their romantic feelings for each other, and as soon as they act on their feelings, they both forget.
Crystal joining the agency means that for the first time, someone is close enough to the boys to notice all this. As soon as Charles admits his feelings for Edwin, both of them forget the stairway confession in Hell and the reciprocation and go back to being repressed best friends. Crystal, who's been listening to Charles hash out his feelings for weeks, knows this is fucked up, and sets out to fix it.
+ Crystal enlists a very confused and skeptical Edwin to break the curse. ++ They regain all the lost memories. +++ Charles fell first the first time. ++++ Charles senses the curse somehow, so every time they go through the cycle, he resists his feelings more, because on some level he knows giving in will cause them to reset. +++++ Niko's back; she can't miss watching them fall in love twice!
