くぐ, ひそ, もぐ
A tsunami carries a husband and his husband up into the sun where they conceal their centaur. The two husbands run a centaur farm, but the local government isn’t too pleased by this so they have to conceal their centaurs in the sun unless they want them to be confiscated by the government.
What is it the husbands are going to conceal? Oh that’s right, a centaur (せん). They are concealing a centaur in the sun. How forgetful of you.
