This role-play is performed by adults. ``I loved my son as a man.'' Natsu, a mother, goes to take care of her only son, who has moved to Tokyo to attend university, once a month. I can only understand my feelings for my son after we are apart. It didn't take long for the abnormal parent-child love that they had harbored for many years to turn into heterosexual love. This can't be allowed. We have to go back to being a normal parent and child as soon as possible...but what should we do now...? After thinking about it, Natsu decides to move to Tokyo again...
