Ikeman Oukyuu◆Mayonaka no Cinderella: Oushitsu no Kishi-hen

“You are now the princess elect of this kingdom.” You were just a commoner visiting the palace. But in a twist of fate, you were selected as the kingdom's princess! What awaited you was an encounter with the captain of the royal guards. “I swear to stay by your side and protect you for the rest of my life.” A vow that the captain secretly made to you. Who will you, the princess, choose to be your prince? Nothing can break this spell—not even the midnight bells. (Source: POCKET COMICS)
