Warm and Cozy is warm and cozy.
I'm not saying it's the best drama in the whole world, there are actually things about it I didn't like, but it is something light and quite cute. If you're looking for something easy that could make you laugh (and sometimes die of cuteness) I think this is the right drama for you.
It's nothing too complicated, so if you want something deeper watch another drama.

PS: What I particularly loved is the OST. I think you'll love it!

PPS: You'll fall in love with the location. It's stunning!
