Do I, Who Only Know Healing Arts, Want to Defeat the Devil?

When Morven woke up, he found that he was in a strange place, and then he was penetrated by a girl he had just met. From now on, life in a different world with hell-level difficulty begins—— A cultural novice, he doesn't know the language, he doesn't know the martial arts, his physical strength is extremely poor, and he can only use magic to heal! What did you say? The devil is resurrected! I'm not a hero, so why should I defeat the Demon King? Wouldn't it be better to leave this kind of thing to the brave?
