Yuuta has invited the members of his club to dinner at his home to meet his nieces. Shuntarou is overwhelmed by Miu and Hina, while Raika is smitten with Sora. Life with Yuuta and the girls have become routine, and what to do about the upcoming school term was the next family problem. But a visit from the Landlord has changed everything.

With only a month to find a new place to live, Yuuta is under the gun. The new place must be within distance of daycare for Hina, trains for the girls, and affordable. Finding such a trifecta will be hard even with the help of his friends. They need an extension of the eviction and Hina might be their weapon.

Yuuta and the girls win a family trip to a hot spring resort, where they unexpectedly followed by Raika, Kouichi and Shuntarou. As they spend time at the swimming pool, Sora becomes concerned that Raika might have feelings for Yuuta. She gets more anxious when she believes Raika wants to take Yuuta to a Lovers' Cape, though in the end, it turns out she wanted to take Hina. The next day, everyone goes to the Lovers' Cape to ring the bell together, making a wish that they'll all be together forever.
