TONIKAWA: Over the Moon for You

Does a marriage need a wedding? The Yuzakis grapple with that question, as Nasa learns just how daunting the ceremony can actually be.

Old friends resurface in Nasa's life, as he introduces Tsukasa to his old teacher Yanagi Naoko.

Tsukasa and Nasa head to a big-name theme park, where they have a run-in with Nasa's old teacher, who might be in the middle of her own romantic encounter.

Nasa's knowledge is a big help to the people around him, but even he's not sure about the list Kaname finds on the internet that describes the symbolism behind different kisses.

Thanks to Kaname, the Yuzakis find themselves on a honeymoon trip to Kusatsu, home to some of Japan's most famous hot springs.

The Kusatsu trip continues, but will Nasa work up the courage to ask Tsukasa to join him in the hot springs?
