Enmusubi no Youko-chan EP3 - Sworn Treasure

Gessho and Unhi follow Setsuyo and Fuuki on their date, using the memory mallets to continue to return the memories of Setsuyo's former life to her. Unfortunately, nothing goes quite as smoothly as planned and Gessho begins to suspect there's more here at play. Unhi needs to marry Setsuyo in order to regain his place in the line of succession but the universe and even Unhi's own servant seem to be against him being reunited with his love.
