I feel like they could've just finished at season 2. Part 3 felt like it dragged on. It was going back and forth with the revenge and Dan Tae and Seo Jin always escaping or killing more people only for all the good main characters to have their happy ending in Heaven. I'm totally okay with that but it was kinda like what was the point? They went through a lot of BS. The kids ended up losing all their parents. They should've died earlier then if that was the case and end the drama. I felt like the author was really money hungry to drag it on. Well at least all their kids add happy endings. I loved the character development of all the kids when they're grown up. Ro Na is super successful,
