From what I’ve seen so far the FL can come off toxic but I believe the demons she’s fighting with emotionally bc of her past is the a major reason. Does it excuse her behavior, no, but it's understandable. The drama so far has touched basis in different aspects of autism, personality disorders and other mental disorders. It’s also nice to see there’s romance, but it’s not the main focus. It looks like a drama that focuses on mental illness and the healing aspects that will help bring awareness behind them. The main characters look to have different but similar pains in their childhoods and from what I see they’ll help heal each other’s wounds and grow to love each other. I have also heard some may view this drama a bit toxic or lack of plot depth. But from what I’ve seen so far I haven’t seen much to complain about. But what drama is perfect? For me, I feel this is a drama I’ll watch until the end, re-watch or even buy for my fav drama collection. This review is my opinion of course. To those watching, give it a chance at least. If it’s not for you, that’s fine. Happy drama hunting to all.
