I totally get why you'd be looking for something similar to 'My High School Bully'—it’s that perfect mix of drama, tension, and a splash of romance that keeps you flipping pages. If you’re into stories where past grudges resurface in vivid, full-color panels, you might enjoy 'Orange' by Ichigo Takano. It’s got this emotional depth about second chances and regrets, though it leans more toward bittersweet than outright revenge. The art’s gorgeous, and the way it handles time travel to fix high school mistakes feels surprisingly fresh.
Another pick that’s darker but equally gripping is 'A Silent Voice.' It tackles bullying head-on but with this raw, introspective vibe. The manga’s watercolor-esque flashbacks and intense character arcs make it unforgettable. For something lighter but still packed with rivalry-turned-something-more, 'Kimi ni Todoke' is a classic—slow burn, but the payoff is worth it. Honestly, half the fun is hunting for hidden gems that hit the same notes!
