First, lets address the acting of the ML which could be compared to that of a dead fish, though I would argue that at least a dead fish has more emotions than he could ever portray. Was he happy? Sad? Shocked? Disappointed? I'll never know.

Second, lets address his character which somehow was even worse. Firstly, he lies about losing his memory because he wants the FL's shares (which she is unaware of) I assume to take over the company. Secondly, after she nursed him and gave him a home, he leaves her and then when he shows up out of the blue he expects her to be jumping for joy. On multiple occasions he crosses boundaries that she makes very clear she does not want crossed. their are so many awful occasions but the last straw when he forces his way into her brothers apartment and tries to button up her shirt. when she says that she can do it herself he insist upon it as if she isn't a whole grown women that cant do a simple task.

Next is the dialogue which honestly you can tell they tried to make romantic but it just came of as cringy and predatory. And although the plot is filled with clichés that doesn't usually bother me if its done well, but for this drama its like they just were throwing random tropes in for the sake of there being a trope.

I feel bad for the rest of the cast because their acting was actually good and there was a lot of potential but the ML ruined everything.
