The Beautiful Stand-In Ran Away in the Middle of the Night

[Two male leads + angsty romance + the groveling pursuit of an ex + showbiz]

Yesterday is gone and can't be kept; affection that comes too late is worth less than grass.

You treated me like a substitute and still expect to win me back by groveling???

Sorry, I'm not even letting you touch the dust I leave behind!!!

Since you treated me like a toy, I'm going to pick a more obedient younger guy instead!
