helpful tip: almost all manga that are based on a novels have the same name as the novel, so to find them you just need to copy&paste the title of manga in google, type novel next to it, click search and voila, there it is ٩(๑❛ᴗ❛๑)۶ usually it is on the page NovelUpdates.com that is one of the first search results so you can find it easly ヾ(❀╹◡╹)ﾉ~ but since I went and did it already for myself here it is =): https://www.novelupdates.com/series/death-is-the-only-ending-for-the-villain/
TYSM!
I read the novel and I actually really like it. I was a bit hesitant about starting it because of the first chapter but it was much better than I expected. Her story is a bit heartbreaking to read about though.
