@tanjirofanforever omg I absolutely love death is the only ending for the villainess!! There's so little fan fics of them, I got a few but here is two (I actually have a few chapters written for them too on my doc actually haha ヾ(^-^)ノ)
1. It's a crossover family, I absorb love crossover families if you can't tell, it's where Killian and Ayla are the parents and their children are Hilisie inouden(from untouchable Lady) cale (from trash of the counts family) and of course Penelope (from death is the only ending for the villainess)
2. Is where when Yvonne got lost she met Penelope and Penelope helps her get back to the Duke and in return she (Penelope) gets to be an Eckhart as a reward (idk why but i was thinking for the ending of this one is that Penelope died and Yvonne got back in time to try and save her, basically instead if the lady love love project game/harem game it is to save the "villainess" From her death etc etc)
