After Becoming an Immortal, I Became Everyone's Favorite

She used to be a poor, unfortunate little cabbage, but then she suddenly gained magic and became everyone's darling, like a little flower. The twins of the richest man in town were even willing to become her underlings. They actually paid her a salary, too. Her favorite idol kept hovering around her, and it turned out to be because of the awful entanglement from her past life that made her want to throw up. What do you mean I have to catch ghosts, subdue demons, and exorcise evil? What do you mean I have to cultivate, get stronger, and fight monsters? Whatever, as long as you spoil me, I'll marry you... Never mind... I'm immortal now, so I'll worry about the future when it comes.
