This show has set the bar for Asian dramas for me.
Realistic, sweet, funny, heartbreaking, bittersweet and romantic.
The actors who play the FL and ML are brilliant. The connection between the two is amazing. The interactions are so natural and charming that it looks like entire scenes were ad-libbed by the actors. I wouldn't be surprised. The scenes between the FL and her brother are the same -- completely natural and adorable. The subtle physical comedy that Zhao is able to do, playing off her costars into those scenes is amazing. Just a few tiny examples: the wedding scene with her brother when they're at the table - the look they give each other while they're clapping; her expressions with the missed kiss at the skating rink. Whenever she watches the ML do something, her expressions of confusion are hilarious. I haven't mentioned the actor playing the ML yet, but he did beautifully in this drama too. The ML is roguish, loveable, heartbreaking. Will watch this again.
Special mention to the actor that plays the brother. He made his character hilarious. And the child actress: brilliant. Hope she is in a lot more shows.
