I activated the Kissing System.

For three years, from the age of 15 to 18, I was compelled to kiss someone daily.

Without exception, every single day.

If I failed to do so, the system would erase my existence.

The person I had to kiss was Jiang Li.

Someone who despised me to his very core.

My name is An Sui.

By sheer coincidence, I discovered that I was actually a character in a novel.

Naturally, I wasn't the female protagonist.

I wasn't even the malicious second female lead.

I was merely a minor plot device to advance the story.

In the original narrative, I was a nightmarish presence in the male lead's childhood.

Jiang Li, the male protagonist, was raised in the An family from a young age, tormented by my brother and me.

The Jiang family had fallen from grace a decade ago, and out of compassion, my father allowed Jiang Li to stay with us.

However, Jiang Li's status in our household was lower than that of a servant.

Just days after his arrival, he became my "plaything."

I was his nightmare, someone he wished he could banish immediately.

The most dramatic part was yet to unfold.

To exact revenge on me, on my 18th birthday, Jiang Li brought home a girl.

A girl whose features bore a striking resemblance to my parents.

She was An Yike, the female lead, the true daughter, while I was the impostor.

After my birthday, my parents cast me out, never to cross paths with Jiang Li again.

Years of pampering left me ill-equipped for survival, leading to a life of misery.

Jiang Li spared my life - perhaps the only mercy he ever showed me.

On my 15th birthday, a voice calling itself "the System" echoed in my mind, claiming it could help me escape my predicament.

Until my 18th birthday, I had to kiss Jiang Li every day.

Not a single day could be missed, or the system would erase me prematurely.
