What a great recommendation you made, because it's an anime that handles a not-so-common topic in a super sensitive and beautiful way. The dynamic between Ganta and Isaki is the sweetest thing. You're absolutely right—the way insomnia brings them together, giving them that safe space in the old astronomy club, is the heart of the series. It's not just a romance, but a story about finding someone who truly understands your vulnerability. When they finally manage to sleep together, in the silence of that room, it's a moment of relief and tenderness that reaches out to you.
