保母さんといっしょっ！～双子とできるもん！～

Reunited with a cheerished mentor and her adorable twin daughters, Yuuji hopes to repay his newest employer’s kindness with devotion and outstanding performance. Yet to successfully embrace the future, he must first settle the past. Feelings old and new, hidden and exposed, have begun to surface in Yuuji and his friends: emotions that have long been waiting to be satisfied and laid to rest.
