After the Wicked Supporting Actress Becomes a Sister-Con

The Junior Demon System binds itself to Mu An’an, an innocent, kindhearted girl who’s a little slow on the uptake. From then on, Mu An’an becomes a total big-sister fanatic.

“An’an, your mission is to steal the female lead’s luck and stop her from using cheat abilities. Hurry!”

Mu An’an understands: “Whoever steals my sister’s luck, I’ll beat you up!”

The Demon System is speechless. “I told you to steal the female lead’s luck!”

Mu An’an understands: “Then I’ll steal the female lead’s luck, I guess. Just don’t steal my sister’s luck.”

The Demon System: ???

“Then if your sister isn’t the female lead, what is she?”

“Obviously, she’s An’an’s big sister~”

What do you do when you bind yourself to an absolute menace? The Demon System sobs.

The female lead is sweet on the outside, dark on the inside; the male lead is a loyal puppy; the second male lead is a total psycho. Everyone is smart and capable.
