A male kindergarten teacher transmigrates to a planet inhabited by insectoids and becomes a commoner male. He not only finds an insect egg in a garbage dump, but also goes back to his old profession. He spends his days peacefully cuddling the little ones at an insectoid kindergarten and soaking up the sun, perfectly content with his life.
Later, the insect egg's parent shows up, but insists that he marry him.
"You took my egg, so now you're my husband."
The protagonist is the weaker one in the relationship, while his partner is stronger. This is an unconventional insectoid setting where male insectoids are no longer so rare and precious.
Theme: Taking early childhood education seriously.
