If you don't like the typical teacher-student romance with a bit of mystery, this is definitely not for you. In the first few episodes, you will be annoyed with some characters, but if you continue to watch, you will understand them. Personally, unlike the other viewers, I didn't feel that much chemistry between the leads. I didn't even care if they would be the end game or not. It's not that I hate them. They are just so blinded by love that it's ridiculous sometimes. The female lead's words, "I will still love you even if you are my stepbrother," threw me off. I knew it was impossible for them to be siblings, but still, it's kind of disgusting to hear. The characters are not that likeable, and when I say characters, I mean most of them. The plot twists are pretty predictable since they are constantly dropping clues and everything else. The male lead is immature and aggressive. The female lead confused me so much with her intentions. I thought at first that she was smart, but she's also naive. About the family history and the mother itself, they were not as problematic as I thought it would be. Although the mother was not likeable, she didn't deserve so much hate as well. She's just being a mother, sadly her ways were wrong. Nevertheless, it's not that bad, but I would not recommend it, especially if you don't like this kind of trope. But if you don't have anything to do and don't mind this trope, it's a pretty decent time killer.
