It's interesting to see this here. I love that you read this manhwa; a few weeks ago, I reviewed it. The story has already ended. The relationship between the main characters is very yandere, so toxic that it surprises you.

I hate Michell and Princess Dulcinea. They're two pieces of shit together, two of a kind. Reinhardt seems mature, but she's really the opposite. She lets herself be carried away by her superficial emotions. It's not good for her.
