The Protagonist's Sickly, Beautiful Younger Sister

My upcoming novel, A Day in the Life of Running an Ancient Inn. Blurb below.

After dying, Lin Hui bonds with a System and transmigrates into the story as Lin Shuyuan, the intellectually disabled younger sister of the protagonist.

She thinks she'll get to spend her days eating, drinking, and having fun, but the System tells her she has only one year to live. To gain more time, she has to complete missions.

To survive, she has no choice but to shamelessly curry favor with Shen Yi'an, the story's second male lead.

Her progress is slow, but fortunately, the System is there to help.

System: "I can give you a golden finger."

Lin Shuyuan: "A golden finger? That's a great thing. Can I have one?"

System: "Of course."

So she got a golden-colored finger, and it was the only one she had.

System: "Congratulations on completing the mission. You have received one mysterious gift pack."

Lin Shuyuan: "A mysterious gift pack? That sounds reliable."

System: "Congratulations! You have received the title of Frail Female Supporting Character and the skill to cough up blood without dying."

Lin Shuyuan: …Can I get a different System?

Ongoing novel: A Day in the Life of Running an Ancient Inn

Qin Zhan-zhan opened an inn in the middle of a desolate village.

The inn was dilapidated and barely provided shelter.

The System told her she could draw one card for free every day.

Then she drew a packet of frozen dumplings flavored with tomato and egg.

???

Frozen dumplings were strange enough, but tomato and egg flavor?

Theme: Even when faced with utter despair, never give up hope
