Kill Me Heal Me ( ML has multiple personality disorder, and FL is the one who will help him)

Love Between Fairy and Devil : His emotions were locked, but she's able to make him feel again!

My Roomate is a Gumiho : He's a gumiho that wants to turn human, but the FL acidentaly swallows the pearl that can make him human so he needs her, to mahe his dream come true.

The Princess and the Werewolf : Similar situation to the one above.

Shadow Love : The ML is turned against his will into a shadow puppet and only the FL's blood can help him survive, and being next to her makes the pain in his body go away.

The Atypical Family : He has a superpower, but lost it due to depression, and FL helps him not only get it back but also she becomes the key to his power.

It's only fantasy, but I hope that helps! :)
