I really believe this to be an underrated gem. I think it's probably aimed at a more mature audience so if you like cliche romcoms that don't really have much plot rather than boy meets girl and they fall in love, you probably won't enjoy the mature themes in this drama.

I found this to be a great healing drama. The character of Nam Se-hee seems a bit eccentric and unbelievable when you first start it. He wants a clean, non-smoker, non-noisy roommate to feed his cat and do the recycling etc. He even tells his boss at one point that he can't work any overtime because his previously roommate moved out and he needed to go home and feed his cat. Enter Yoon Ji-ho. After a mix-up, she is the perfect solution to being his tenant. She is clean, she feeds his cat, she recycles and goes above and beyond in keeping the apartment clean and even cooking meals for Se-hee. They enter into a marriage contract where she gets to stay at his house as a tenant while helping him pay off his mortgage and it's only meant to be for two years (?) Obliviously, they fall in love and things get really complicated. Se-hee has a painful past and he is has closed himself off to love. But their love story between the two leads is so beautiful and their kisses are some of the best I've ever seen.

There are also two other side couples which interesting storylines. I really like how this drama focused on the different struggles and expectations each couple had while being in their 30s. Like I said early, this drama is definitely pitched for a more mature audience so it might not be for everyone, but I thoroughly enjoyed it and would watch it again. The acting was good, the story moved at a good pace. There were no boring filler episodes or dragged out storylines.
