This is a surprisingly engaging and well constructed series. There is a realistic but not painful love triangle then the dating after that which keeps things interesting to the complete ending. The characters are likeable even the mother who is a refreshing change. No contrived villains. The age is the main obstacle but I like the way they dealt with the issues in a funny but not heavy way.
Uhm Jung Hwa makes her character a sympathetic feisty and likeable career woman. It could easily have been cringeworthy if she overdid it but she doesn't. And although she is actually 20 years older than PSJ it didn't feel icky or wrong.
Park Seo Joon displays a range of acting talent here from good comedic timing to passionate love. Fight for My Way is still PSJ;s best show but among the rom coms A Witch's Love is the most engaging. She Was Pretty was painful and
Secretary Kim was simplistic.
One of the few faults is some of the acting cute and in love was borderline painful but these parts are brief. The director of this show did Crash Landing so you are in good hands. Worth a watch.
