Arelyn Is Sick and Tired

Reincarnated as an extra. The male lead's non-existent childhood friend, an extra who dies early in the novel. It's time-limited, so I can't avoid the dead flag. That's why I'm living... “Why aren’t you healthy?” “I mean, be healthy.” “Why are you hurting again? I asked for permission to get sick again.” Namjoo has become my health obsession. Oh, please get the male lead away from me!
