I was forced to cross into a fairy tale and became a vicious female supporting character who was destined to be stepped on by the male protagonist and eventually die miserably.
In order to survive, I was bound to a 'Mother System'.
The system said: As long as I do good deeds sincerely, I can gain merit points and avoid the death flag.
So with tears in my eyes, I endured the pain, picked up the artifact that the male protagonist had dropped, and returned it to him, and gave the secret realm treasure to the male protagonist's junior sister.
But later, when the male protagonist was devoured by thousands of demons in the Abyss Demonic Realm, and the little junior sister was corroded by the poisonous mist and her life was hanging by a thread, I slowly took out the magic weapon they had 'left' with me.
"Don't worry," I smiled gently, "I'm coming to save you 'sincerely'."
Only then did I realize that the poison I had concocted seemed to have accidentally... Poisoned the Demon Lord to death.
Intention: Who said you have to be sincere to earn merit? I pretended to be real enough that the system couldn't tell the difference. What I want to write in this article is: I have worn the mask for a long time, and it is up to me to take it off or not, but I have the final say on every transaction in the account book.
