Harem Marriage volume 13

Yuzu has big news for her husband Ryunosuke and her sister-wife, Koharu: she's pregnant! Koharu is excited to welcome the newest addition to the family, but Yuzu, tellingly, seems less than thrilled. Just as Koharu's suspicions begin to rise, Yuzu's brother, Hassaku, pays a visit to the Date family home, hinting that his sister might soon ask for a divorce. The reason lies in a trip down memory lane into Yuzu's past, well before she met Ryunosuke... And the answers therein could save the Date family just as surely as shatter it.
