Engage Kiss is a show that starts as a generic harem comedy and slowly reveals itself to be a tragedy about sacrifice, obsession, and the cost of revenge. It's not perfect—the middle stretch drags, the conspiracy plot is underbaked, and the finale rushes to a resolution that doesn't quite satisfy. But the core relationship between Shu, Kisara, and Ayano is genuinely compelling, and the memory-loss mechanic gives the show an emotional weight that most harem anime never achieve. If you dropped it early because Shu was unlikable, it might be worth giving it another shot. The show knows he's unlikable. That's the point.
