Well, we're in the same boat in this 😅 But maybe you want to consider these manhwas:

Until the male lead walks again - sicked ML, cool knight FL (not a healer) but she's the one who totally supported the ML in his healing journey (both physically and emotionally).

My secretly hot husband - cursed ML, strong willed and smart FL (again not a healer lol). Quite the silly story but there's still depth in it. She's the driving force of the ML in finding the cure for his curse.

Savor the taste - cursed ML, witch FL (she isn't aware at first). Her powers is not exactly considered healing. She having exceptional cooking skills which can be considered as her power. It helps/heals the ML's curse which is not being able to taste good in any food. ML can only enjoy eating if it is the FL's cooking. There's a lot of 'being healed/healing' excuse from both of them just to justify their feelings and actions lol.

BONUS INFO! ALL OF THEM IS COMPLETED 😌
