Moon Lovers: Scarlet Heart Ryeo was set to be a popular show from the very beginning, as many drama lovers were tuning in for the very familiar faces. Moon Lovers had a star-studded, and very handsome cast. From Kang HaNeul to Ji Soo, the princes were real life prince material. The relationship between IU and Lee Joongi, the fourth prince, was adorable, and the characters were very likable. Moon Lovers was silly but had just enough drama and serious moments to become really popular. Even if EXO‘s Baekhyun‘s death in the drama did break our hearts, Moon Lovers was good enough to stitch it back together.
