Souta is sleeping with a tossing and turning Poco when his longtime friend Nakajima Shinobu shows up for an impromptu fishing trip... at 3 AM. The trio cast their lines under the Red Lighthouse, but the fish just aren't biting. With a bored Poco playing nearby, Souta and Nakajima have a heart-to-heart about their thoughts on marriage and the future. When Souta sadly reveals that he might sell his childhood home and restaurant, Nakajima presses him to take over the restaurant, but Souta won’t give him a clear answer. Will Souta go through with selling the house? And what about Poco?

It's a lazy day at Souta's house when Nakajima abruptly reveals that his mother guilted him into agreeing to a marriage interview. He's thirty and still single, and Souta's stuck in the same boat. Rinko on the other hand is already married, but not exactly a perfect homemaker. So when she offers to make the boys lunch, they realize she's acting strange...

Excited by the festival fireworks display, Poco accidentally lets his tail out in the middle of the crowd, in full view of the cameras. Does this spell the end for Souta and Poco's little family...?
