Asa Okitara Tsuma ni Natte Ninshin shiteita Ore no Report: Kosodate-hen

Seiichi Ito's wife asked for divorce, saying, "You are useless for raising kids."
In a panic, he fell down and woke up to find that he was in the body of his wife, having just given birth to Ko-chan!
"Ko-chan will be fine!" "Just relax!" "What should I do?"
......He thought he was helping with child-rearing in his own way before, but it turned out he didn't understand anything...?
Seiichi, clumsily but clumsily, began to raise his child in his wife's body while being frustrated with his carefree original "self." Will he ever be able to get back to his ideal "family of three" life?
