Quick Transmigration: Love on Assignment

After working herself to the point of exhaustion, Wen Yiyue died suddenly. She signed a contract with the newbie System Yeye, and together they traveled to different worlds to start sweet romances with different male leads. (Some worlds have clients, while others don't. The female lead will prioritize the clients' wishes.) Note: The first world went off the rails, so don't read it, don't read it, don't read it!!! (Please be patient with me, I'm a complete beginner!)
