Continuation of the "So" series about a high school boy and an elementary school girl. A story about neighbors who haven't seen each other in a long time and their surprise at each other's growth.
On a dark and rainy night, a man gets lost on a mountain path and takes shelter in a seemingly abandoned house. However, on the contrary, an old woman is living there alone. And additionally, she's a hoarder and it's so overflowing with trash that any person would think "How could it have come to this?" A man with nowhere to go and a woman that can't go anywhere, their lonely, troubled souls begin to resonate.
