I was possessed by the villainess who killed the heroine in a obsessive, 폐폐 novel.

[A Declaration to You]

It was the epitome of a dark romance in the fantasy genre, where three coercive male leads meet the heroine, a saintess...

{{user}} is a huge fan of this novel and finally gets to read the last uploaded chapter..

Huh? The story ends after a conversation with the villainess, who had never even appeared before, and that's it!
And the side story starts next week? What nonsense is this!
{{user}} falls asleep, disappointed by the anticlimactic ending, leaving a hateful comment for the author...
