I Debuted After Becoming a Sickly Female Supporting Character

Description

Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

In a Jinjiang novel, the powerful Cheng Yue kept a girl in his villa. She had delicate, flawless skin, excessively beautiful yet melancholy eyes, and an air of frailty reminiscent of retired actress Dong.

The girl was a stand-in for Dong.

Upon discovering the truth, she jumped into a river. She survived, but the boy who saved her died, leading to widespread condemnation online.

Meanwhile, Jiang Su was a side character in an external novel, a killer with a Mary Sue assassin aesthetic enhanced by that world’s setting.

Unfortunately, she transmigrated right into the river-jumping scene.

As concerned onlookers shouted for help, they turned back—only to see the girl climbing out at full speed, wiping her face: “I’m fine. Just admiring the scenery, slipped a little.”

From that day on, Cheng Yue’s frail beauty was gone.

A month later—

A struggling idol group made their first appearance on The Talent Show Girls.

The members stepped aside, revealing a delicate and melancholy girl in the center position.

The audience sneered. So weak and fragile, like she’d fall over from a breeze? What could she possibly do?

The next moment, they watched in stunned silence as the girl bent down, pulled a suona (Chinese horn) from her bag, and dominated the entire stage—going viral across the internet.

Audience: ???

Cheng Yue saw Jiang Su again at the finals, where the host asked her, “Do you have a gift for President Cheng?”

Jiang Su pulled out her suona and played a song famously associated with funerals, “The Tune Plays, the Cloth Covers, and the Whole Village, Young and Old, Waits for Food to be Served.”

Cheng Yue: …

That year, Jiang Su was voted “Your Dream Lover” No.1 by both male and female voters.

A super cool, unstoppable, overnight sensation of a girl × A gloomy, jealous, passive-aggressive male lead. The male lead enters the “chasing wife in the crematorium” phase.

#What happens when a lunatic becomes a lover#

[The female lead is a killer side character from an external novel who transmigrated into a Jinjiang novel. She’s ridiculously capable, highly professional, skilled in everything, and transmigrated before she ever got to kill anyone. The stand-in was never real.]

One-line summary: An assassin side character from an external novel transmigrates into a Jinjiang novel.

Quite satisfying. The FL is a Mary Sue but! At least, it's backed up by her hard work and the difficulties she suffered in her past life. So although she almost know everything (almost, because she's not good at finance just like as she mentioned), it's understandable because she learned all of those in her past life in exchange for her life (somehow).

Anyway, although it was quite confusing how she, a previous trained assassin, became a top idol, it's somehow understandable given the setting of the story.

As for the romance,... more>> the FL wasn't that dense, she just didn't experienced any kind of love in her past life. Therefore, she was quite confused and loss at what to do when treated with kindness. Nevertheless, once she understands her feelings, she's not shy about it. As for the ML, the most frequent word used to describe him was gloomy. So I don't really know how to imagine his face. Even when he's being sweet with the FL, the adjective used to describe his face was still gloomy. Anyway, aside from that, the ML was kinda confusing? I don't know how to describe his character. I don't hate his character design but neither do I like it that much. Also, I think it was too much of an exaggeration to call the ML as psychopath (since it was mentioned that he was diagnosed as one after being kidnapped). As for antagonists, not that much. The most mentioned one was the supposedly white moonlight of the ML (which is not true). But even she was like a clown who was face slapped by the ML himself. In short, the FL never really considered these people seriously. Overall, it wasn't that bad. The world background was kinda confusing because this is a world book, what is its theme? Who are main characters aside from CY? It was also mentioned that the FL was originally a side character in her world, but what was the background of the story? The only thing mentioned in her past life was that she's a trained assassin, that's all. Anyway, it's not a story with a lot of loose ends but also not that bad. I think, this story is more on how the FL, who was once deprived of love and kindness, became loved by all. 8/10 <<less
