I'm a sucker for cross-culture love dramas. Usually they flopped because the leads couldn't understand each other. Particularly bad have been some Japan-China or Japan-Taiwan tie-ups. It was pretty clear the leads didn't understand each other.

Most recently there was another Japanese-Korean drama called Eye Love You which was great too because the leads understood each other. However, it soon became draggy and tried to achieve too many things, probably because it had more episodes than were needed.

In this drama, I read that FL learned Japanese for the role and it shows as both clearly understand each other and can react accordingly. This is a simple sweet and short love drama! Fast moving too. Loving it!
