Here's one manga many people hate because they didn't read the tags. This is NOT a comedy, romcom harem manga, but the summary tends to bait the wrong type of reader, so here we are. The real core of the story are the Eniwa twins and their struggle with their mental instabilities. It's an engaging read, if you're able to connect with the characters. It ends in a melancholic tone, with a grim reminder that mental issues don't just go away: You have to learn to live with them.
