this is so bitter. MC fall in love to a woman that he can't have. Yuki Onna have loveless marriage and boring lives. they would eat the crab and go on separate ways after this.
this is so sad, the guy so despairs in life that he really want to suicide, but can't do it because he just found love, but he also knows that what beyond said love is nothingness
Just find out the author possibly a women. Idk why women in seinen mag tend to write good stories, it's really the opposite of women in comic industry which is made me sad
