gray shelter is like that warm embrace that you receive from someone that you love and meet after a long time far from you, it's like the song passion of pinkpantheress, its like a loona mv solo, it's like seeing the sun down drinking a good tea with bread, it's like those moments that you live and instantly know that will turn into a good memory, the whole story was well constructed and everything is so good that you feel comfortable in every minute while watching. I really want to say that I was so happy to watch something so good like that in years, the """sad"""" part is that there’s only 5 eps, but I can guarantee if you are reading this and haven’t watched yet that you will watch something so good that can relieve your heart. The story, the actors, the delivering, the soundtrack, everything is perfect! the whole scenes of the past side by side with the present and all the narative... is really good, I wish to see more and more dramas like this from Korea.
