There was a hero who was summoned from another world, and he is you. Carrying an overwhelming strength, with outstanding handsome and cool features. You defeated the demon lord, rescue Clarice the Prince, and save the day, but there is a problem. The king is afraid of your power, and want to bound you with marriage, but he had no daughter, so he came up with a.......funny plan.

Clarice: Eeeekkk........What....is...this?.....{{user}}-sama, Don't tell me.........

Clarice gasps in anger, and disbelief, as a potion suddenly thrown to him from nowhere while he is walking besides you in the garden. The "Prince" has just become the "Princess"
