Most of the casts' acting was good, ost forgettable, but the story was bland. The premise was interesting, but poorly executed. There is no real chemistry between the leads up to episode 15, with the FL being portrayed as selfish, ungrateful, spoiled, and downright hateful to the ML. Nothing really shown in the flashbacks, ML's history/backstory (has psychic abilities, was the smart kid in high school, attended college with her, and was taken in by her dad to live with them), or in present to explain his undying love towards the fl. The rest of the main cast, apart from the FL's friend and the SML, were entertaining and likeable. The main story only started to get somewhat interesting in episode 14. The side stories and the fun bromance between the handsome ML and his friend keeping me watching more than the so-called romance between the leads. Honestly hated the FL until she finally stood up for the ML at a press conference to keep him from resigning from the project. There is no growth to the leads' characters, their history is limited to brief flashbacks that explain next to nothing.
Instead they apologize to each other after she finally investigates the incident she blamed him for for over 4 years and suddenly she's jealous around other women and acting shy/cutesy around him. The FL has problems acting sad, caring, genuinely sorry, or loving, it came across really insincere and stiff. Pretty much only nailed anger/hate/jealousy, proud/arrogant. The rest of the cast did the best with their parts and carried the show without her. Definitely not worth rewatching as i had to play it at 1.25 x speed to keep from being annoyed or from dropping.
