This is one of those dramas I randomly started watching without really thinking about whether or not I will like it. BUT I LOVED IT. It starts out fun, cute, lighthearted and HILARIOUS. You will be laughing and swooning constantly. Like most kdramas, it gets more sentimental and emotional in the end. BUT IT'S A MUST WATCH. The chemistry is on point, I loved the acting, the setting, the whole vibe of the drama is amazing. Definitely one of the best romantic comedies of kdramas I seen with a hint of science fiction!
