Both the drams are very much the same. Very very similar. I'm sure anyone who like touch your heart will like The beauty inside you. Lot of romance and lot of dialogues.

Both are revenge dramas. Both male leads prepare themselves for a long time to get perfect revenge. And the main reason they both have similar vibe is because both the male leads never lose their game throughout the drama. Although some moments seems to have negative effect , it always turns out that it was all master plan of the lead. Money flower is much darker compared with doctor prisoner. They both have very mild romance although Doctor prisoner shows only hints.

The stories are somewhat different. But if you like Hotel king you'll definitely like Triangle. Both are based on protecting someone and the romance in both are good.

Both are the same story of the same person with legend narrating the story with fantasy elements. The story focus on Damdeok later, Gwanggaeto the Great. Although the story is entirely different legend is watchable once.
