I loved the banter between Nikoli and Lily, I think its a cute love story. 
Some parts were pretty cringe,

Lily making Nikoli get new furniture because 'who knows what diseases are on there'. That was absurd.

 
There was one inconsistency that didn't make sense to me, at the beginning Adam briefly wrapped Lily in a hug and a few chapters later he can't even touch her without her flinching or panicking.
