The youngest brother, Hinata, finds his lack of experience in romance a problem when writing the plot for a new manga. He enlist Tsukiyama’s help in find out what his audience would like to read about- however, Tsukiyama finds that she too lacks experience as her last love was in high school.

Whilst the brothers work to get their deadlines met before their annual holiday, Tsukiyama works through the receipts for their expenses and grows upset over the expenses that Satoshi accumulates in comparison to his brothers.

After Tsukiyama’s words with Satoshi he leaves the family home for a while to clear his head. Meanwhile, the other brothers are falling apart without Satoshi there to help. Ichiro and Tsukiyama try ad fix the rift that Tsukiyama has created between the brothers so Satoshi can return home.

The identity of Hanazono Yuriko is leaked and the Kataoka brothers find that they cannot continue their daily lives as they are unable to even leave their home as fans surround the building hoping for a glimpse.

Wataru asks for Tsukiyama to leave as he feels her presence has changed things too much - and not for the better. Meanwhile, Hinata misses Tsukiyama and the feeling his brothers are hiding something from him grows stronger…especially with Misuzu still poking around.

Osamu finally gets the courage to ask Minae on a date and enlist Hinata’s help in planning it. Meanwhile, Misuzu makes her move and the secret that has being kept from Hinata is exposed in the paper with a few twists on the truth.

Hinata reacts to the knowledge that he is not a Kataoka and that his birth father had his work plagiarised by his adoptive father. His brothers, Tsukiyama, Ryoko, and Ichiro are frantically searching for Hinata before he can do something he will regret.
