Su Qiyu got tangled up with a shady holographic game System. It said she had to transmigrate to various worlds, experience the games, and reach their endings. All she had to do was keep the player alive. Easy, right? Su Qiyu had no desire to go looking for trouble and firmly refused, but the shameless System just wouldn't take no for an answer.
In the end, with no other choice, Su Qiyu accepted and laid down all sorts of unreasonable terms. The System needed her, so it had no choice but to agree. And so Su Qiyu set off on her gaming adventure.
One-on-one romance throughout. The male lead is always the same person. Not sure if the golden finger is too powerful, but if it feels excessive, it'll be toned down a little later on.
The female lead isn't a naive sweetheart, but she'll play one when she needs to. That's pretty much the gist of it.
