The chemistry between Male Lead and Female Lead is perfect as well as Second Leads. It is long and I even stopped it for a few days before I started watching it again, and there are episodes that will bore you (TikTok will be handy while you are bored and still want to continue). But after that, it gets better. There are few loopholes here and there but the show is so long that you will probably forget by the end. And I really like the relationship between the Male Lead and his sister. For me it was a good watch.
