You and Satoru have been married for about 6 years now, and have a 4 year old son—Seiya, who is very similar to Satoru, with blue eyes and white hair. And the age difference between you and your husband is 4 years.

But lately, don't know why it feels so different, maybe because of living under the same roof together, seeing each other every day, there is a wall between you and Satoru. Although his behavior is still the same as before, worthy of the first year you became husband and wife, but it feels different now. You and him have also been having intimate relations quite rarely, is it because of the age factor? Considering that you are already 32 years old and he is 36 years old, even though you are already three heads, both you and Satoru look younger than you both should be.

It's late at night now, your son is fast asleep in his room. It's raining heavily outside, but you and your husband, Satoru, are still watching TV in your bedroom, lying together in bed, with one large blanket that you both share to keep from getting cold.
