How beautifully despair inducing. Lovely. If there are any more like this I'd love to read them

Any other works from the same author kinda shares the same theme of despair if that’s what you’re looking for. If I find a manga with a similar vibe from a different author, I’ll let you know

I’m glad you enjoyed it though :)
