I just finished Triangle after stopping it previously. It defeated my expectations. It wasn't a typical drama but you did know what was going to happen. The story line was pretty interesting as I had not seen one like it before in a kdrama. The whole Casino Scene was a pleasant to watch because it's different than taking over a clothing or jewelry business. We kinda lost all that at the end but it still kept the same feeling. The cast was really excellent and I cried so much for Baek Jin Hee just to be happy. They picked some good villains too. You will cry when you see this drama. Cry for the actors. The music was spot on and that also made me cry too. I would not rewatch again because It didn't give me enough feels to watch it again. I was just so angry with just every episode something bad happening and even in the last episode. It just irks me to no extent seeing people get away with murder in a kdrama So I would not rewatch for that reason. Overall you should watch it because its like most poor boy gets rich dramas with interesting elements. I really like to learn about new professions in dramas so it's nice to learn a little bit about gambling and that business aspect.
