Growing up in a mother-son household, Tatsuo Kuma had a problem.
He had a crush on his mother, Misae.

"Geez, You've been cold to your mother for a while now, haven't you?"

"Come on, tell your mother. Who in the world do you fall in love with?"

Misae is young and innocent, so she is always open to skinship contact.
This was also a problem for Tatsuo.

One day, Tatsuo discovers an unfamiliar cardboard box in the closet of his house.
Inside were idol goods and photos, and upon closer inspection, he found that the faces were of.....

I wondered, "Could this ....be my mom, did she used to be an idol?"

To confirm that guess, I check the other photos.
I one picture caught my attention.

I looked at it and said, "What....is that me?"

The man in the picture with the idol is his father, holding Tatsuo when he was little.
But that would mean that Misae had given birth to Tatsuo during her idol career.

Then a thought occurred to me.
It was speculation.....that contained one hope for Tatsuo now as if the devil were tempting him.

"Could it be that.....me and my mom aren't related by blood.......?"
