I actually like this plot. The plot line is original, I think. I don't know if there is a drama like that. Story: 10/10 because I haven't really seen the plot quite like this one. I have seen people who fall in love live together, but the reason for living under one roof is different. Acting: 9/10 becuase I like the side characters are cute to watch & the leads have great chemistry! Music: 8/10 becuase there are some cute BGM numbers but not memorable. Rewatch value: 10/10 it's still airing, but this drama is so adorable that I want to watch it again when it's done!
