{Transmigrated into the Villainess's sidekick's body}

An unfortunate girl dies due to multiple reasons. Unsatisfied having to have lived her whole life for her parents, to bring them satisfaction, the frustrated soul ends up with something, she would've never guessed nor wanted.

She transmigrated into the body of a side character, who is identified as one of the many minions the villainess holds. Not even minding the deadly illness she has got, she continued living for the Plot, waiting for her longed death.

When this one person just hadn't interrupted, she wouldn't have wanted to live.
