Keita has been in Tokyo for half a year to attend university. His mother, Hana, worries about him as he only ever complains. She comes to check on him. The room is in disarray, and Keita looks like he's about to burst into tears. (He can't do without me.) Hana feels her heart flutter with joy at being relied upon by her son. Meanwhile, Keita also reaffirms his love for Hana during this rare parent-child interaction. The thoughts and desires of the two, who have come together for a brief moment, overflow, and they end up crossing the forbidden line between parent and child.
