Summer has arrived and Naoto, Hazuki, and the kids are looking forward to fun, festivals, and fireworks! Things kick off with a weekend trip to the home of Naoto's mother, who lends some much-needed support as little Minato enters his terrible twos. Then, a stray ball in the neighboring yard leads to the discovery that Shizuku's favorite band is living in the house next door! While Naoto may be keen to make friends with the young musicians, Hazuki's overprotectiveness of his omega mate causes a rift to form between them. Is their bond strong enough to weather this new storm?
