I feel like this drama is very in-line with Sung Hoon's 2 dramas, which are "My Secret Romance" and "Noble My Love". It feels very 2015 romance cliche to me. Maybe because the three of them involves rich CEO male lead, and poor woman, with ML being playfully teasing FL because he wants to pursue FL?

I don't think this drama is revolutionary and memorable, as I watched this in 2021, and came back watching it in 2023 with forgetting most of the plot. However, aside from not being the best script, Zhao Lu Si's acting skills still as excellent as ever. People kept saying that she acts like that in every drama - but what is wrong with that as long as it fits the character in the drama. I also love Liu Te's appearance in the drama as well.

As for the love story, It can be considered rather a mixture between romantic-comedy and melodrama, as it involves some heavy family & business dramas.
The ending feels unsettling for me. For personal taste, I'd like to see some karma for the bad characters, it's just how I am, eye for eye, tooth for tooth. But they don't show Gu An Xin's step sister, stepmom, dad's endings that I'd prefer. Instead, they only show how the sister is living a somewhat decent life, stepmother woken up from bed in a hospital, or the dad who has dementia and didn't appear in the show's ending. For me, I'd like for the dad to admit to his mistakes and apologize heavily for his terrible actions toward his own daughter AND her mom. After all, her mom's death is totally her dad's and stepmom's fault. But no, they get a somewhat decent ending for cornering someone until she's dead. But that's my issue.

Aside from all, this drama feels very hallmark-y to me. But if it's your drama taste, you might enjoy this drama.

Ps. Is it just me or the main leads can pass as a sibling? they both really look alike. Probably because they have similar face and nose structure? and their eyes shape are kinda similar too!
