An amusing, light, funny and feel-good Kdrama with none of the usual tropes and makjang, no annoying in-laws nor rivalries, put just pure and simple, pleasant cast mostly. Fell in love with YSH’s character here, one of the best young actors I have ever seen, so matured and excellent, showing such a wide range emotions, from serious to comical, he’s simply lovable. The FL is equally at par with YSH, endearing with her quirky, feisty and inventive main character, likewise with her portrayal as a robot! I have never seen her before, but she acts superbly in this one! Support cast of “scientists” are funny, too, as well as the FL’s best friend, so hilarious. Splendidly enjoyable.
