I keep seeing people ask for recommendations on this lately, and honestly, a lot of them just recycle the same few big titles. '10 Years That I Loved You' is classic, but it’s more about grief and moving on than a literal reset. For actual do-overs, the one that nailed it for me was 'Mukan Shoujo'—a guy gets murdered, wakes up as a kid, and tries to prevent his own death while untangling his feelings for his stoic childhood friend. The tension isn't just about romance; it's about survival and the horror of knowing how things could go wrong.
Another underrated pick is 'The Reason Why Raeliana Ended Up at the Duke's Mansion'—though it's a manhwa, not strictly BL, the dynamic has that intense, life-or-death partnership. For pure manga, 'On Doorstep' has this quiet, melancholic vibe where a guy gets a second chance to mend things with his estranged childhood friend-turned-lover after a tragedy. The reset isn't a magic button; it's heavy with regret, and the romance rebuilds slowly, which feels more authentic to me than instant fixes.
