You Want to Win Me Back After All This? But I Refuse!

After transmigrating into a book, I was forced to become the female lead's devoted simp. For two years, I did everything I could for her, spoiling her rotten until she turned into a haughty little princess and her character was completely ruined... Now that I've completed my mission, I'm off to enjoy life, but she cries and begs me not to leave? Please, don't tell me you really think every story about a man chasing his ex after she leaves him ends with him winning her back!
