It's been several months since my only son, whom I adored, moved to Tokyo to attend university. Asaka, who came to check on him out of worry, saw the figure of her son, looking haggard and living in a dilapidated room. Feeling sorry for such a child, she ends up connecting her body as requested. The other person is my son. This is wrong... But... why did I feel happy? Asaka spends her days repeating self-loathing, but in order to know her true feelings, she goes to Tokyo again...
