Honestly I don't understand why the rating is so high for this drama. There are 2 major issues that killed the drama for me.

1. Proper casting complete fail
Really no offense to the FL as I've seen her other works, however this is all about age appropriate casting based on the character. Lets say FL's character was around ~22 years old & ~13 years later she should at MOST be in the late 30s. FL actress is 50 and definitely looks older than her age. Literally ALL the other moms looked younger than her. So when there are comments like "Oh she looks too young to be a mom." .... umm she can be grandma status. Needless to say there was zero chemistry between the leads. Scenes were cringe worthy....

2. For a drama that was promoted as a romantic comedy it turned into a dark theme with murder suicide? Whole story line felt forced but predicable.

The only reason I continued is because of the strong student cast and some more interesting characters like Chi Yeol's scretary, the Detective & FL's bestie. This story line would've been better if it was more of a school series like Solomon's Perjury. It's already got the beautiful young talented actors in all the classic student roles. So if you skip literally all the ML/FL's scenes, this drama will be actually enjoyable.
