amnesia

Stiles already had his hands full with the case he was working on for the enigmatic Mrs. B. He really didn't need this too, but there was no changing the fact that he no longer remembered Derek Hale or anything connected to him. And no one could figure out why.

The Soldier remembers this: he wakes up in the snow.

Derek sighed and rubbed his forehead. "What if I told you I traveled back in time to protect you."

There is a handsome man who comes into this room every day to check in on Bum and bring him delicious meals. He’s utterly attentive, propping up pillows and tucking in his blankets around him like a protective cocoon. He smiles at Bum and showers him with kisses and affectionate caresses whenever their eyes meet. At night, the man comes into the room and lies down next to him carefully, drawing Bum close into his arms in a loving embrace and they fall asleep wrapped up in each other like that. Bum has absolutely no idea who he is. AKA: Bum has amnesia and Sangwoo sees an opportunity.
