Sumomomo, Momomo: The Strongest Bride on Earth Vol. 10

Depressed over the slow progress of his training, Koushi spends the day with Sanae to take a break from the world of martial arts, if only for an afternoon. Momoko is worried when she sees her fiancé in the company of another woman, but her concern turns to outright desperation when Koushi attends a summer festival with Iroha at his side. Can Koushi's circle of friends convince him to return to his bride...and to his training?
