I Woke Up to Find My Sister Had a Child with a CEO

[Content warning: The male lead is not chaste. He was very promiscuous before meeting the heroine, so please don't read if that bothers you.] Su Jing, the eldest daughter of the Su family, is in a plane crash and ends up in a vegetative state. When she wakes up seven years later, she discovers that her family has gone bankrupt. Her parents, who have always favored her, force her own younger sister to sell herself at a nightclub to pay for her medical bills. Then the story unfolds just like an urban romance novel: her sister not only sells herself to a domineering CEO, but secretly has his child, and years later gets entangled with him all over again... No wonder people say that fiction comes from life but surpasses it. As Su Jing grumbles, she tries to find some peace and quiet. She hasn't had her fill of life as a rich heiress, and she isn't ready to suffer through poverty yet, aaah!!! But even less does she want to be a sister who leeches off her younger sister. After thinking it over, Su Jing decides to start a business. As she sits in a park wondering where to find startup capital, she sees a young man by the lake trying to kill himself. She tries to talk him out of it, only to find herself saddled with him. After getting to know him, she realizes he's a lunatic, an impossible-to-get-rid-of lunatic. What a tragedy!!! Excerpt: On the other end of the internet, someone has been guarding their phone. When a chat window pops up, they nearly fall off the recliner, their mouth unconsciously curling into a huge grin. Their fingers fly across the keyboard, tapping out a message: [Su Jing, why did you take so long? I've been staring at my phone so long I'm practically cross-eyed~] After sending it, they casually add an extremely aggrieved emoji. Su Jing, on the other end of the chat: “…” Wait, are we close? Could you be any more casual about switching to calling me by my name? And what's with all that thick, clingy sweetness in your words?
