The thing with rating is, that you have different scales, right. I hold this to the standard of other shows of similar length like Semantic Error, Mr Unlucky and of course Star in my Mind (which got 6 stars from me as well).

The plot is simple. Unruly protagonist meets pretty and kind love interest in a rural setting. It's a feel good show with no extreme plot twists or serious conflicts. So I really have nothing to say or comment on regarding the story.
I watched the last episode with a friend who knows nothing about the show and they put it perfectly "This would be perfect for when you're really tired from work and just want to take a nap. Just turn this on and drift in and out of sleep." And that hit the nail on the head I think.

I personally didn't enjoy the acting at all - no, let me put it in another way - The acting made my toes curl. Fah sounded like he was congested the entire time. Like come on, give my boy some nasal spray so he can breathe!! And Prince's facial expression ranged from "no toughts in my head" to "are you fkn stupid?". When I realized it, I couldn't unsee it and made me chuckle a couple of times, honestly.

ALSO I wish they would've tied in them meeting at Daonuea's Freshy Boy competition thing before somehow? I was kind of waiting for that. In Episode 4 of Star in my Mind they ran into each other on the stairs and that scene seemed so meaningful to me but they never addressed it. Not even in the flashbacks or something. Why was Prince even there? Why did he have all those roses? A mystery... (I know the director probably just put it in to tease the love story in whatever way possible but.. you know. A girl can dream of meaningful plotlines)

Anyhow, 6 stars isn't a bad rating in my book. I enjoyed it for what it was but it's forgettable by nature.
