The only good thing about the lead couple casting was that the female lead could actually be mistaken for a pretty boy.

They not only lacked chemistry but their story was so boring. Despite such a interesting trope, they weren't able to hold my interest. I finished all the 40 episodes in 6 hours, skipping to scenes that featured the second couple. Now, these two were so well-written and cast perfectly for their roles. They had amazing chemistry.

In the beginning, I though the SML's resting face was too bland and it just made in look expressionless but when he starts interacting with the SFL magic happens. If it wasn't for my curiosity about what happens in the end and how it happens, I would have dropped the show.
