Its a good novel.
Some things could have been more detailed, so the reader could feel closer to the character and truly grasp where some relationships and interactions stand at certain points of the story, so they understand what some interactions really meant. 
But the writing do a good enough job to let the reader know the general situation of that segment. All in all, the author did a good job. A great job even, considering this is a finished novel, which cant be said of 90% of the novels in this plataform. 
So congrats author, for giving us characters we can follow around, for all the feelings given us throught the story, and for giving us a closure, an end to a good story.
Its been a long time a slice of life didnt hold me in, but this one did, and for that Im grateful... I missed this weird feeling of finishing a slice of life/romance I had when I was yourger, reading manhwas of the same genre.
