It's been half a year since my only son, Keita, went to Tokyo to attend college.His mother, Hana, is worried about Keita, who is always complaining, and has come to see how he is doing.Keita looks like he's going to cry at any moment with the devastation of his dilapidated room. (This child is useless without me.) Hana's heart flutters at her joy at being relied on by her son.On the other hand, Keita also reaffirms her love for Hana after seeing her for the first time in a long time.The thoughts and desires of the two who have met for a short time overflow, crossing the unforgivable line between parent and child.
