I can totally understand why people hate harem but it's far better than half baked romance where there are atleast 10+ girls who fell for MC and interacted with him romantically but he is the Chad *ss who doesn't give sh*t about them.
Good romance is hard to find and even harem is fine unless it's not exaggerated like 6+ people. Then it's kinda off putting honestly. 4-5 people with a good story has a great potential to develop. Let's be honest, over 2000+ chapters, either the romance should be introduced late or it would become extremely boring.
