Erika, Hiro, Sachi and Nagi make plans to study at Erika’s vacation house, but there ends up being a slight change in the roster.

Nagi is hoping to do the test of courage with Hiro, but Erika takes him instead. Nagi can’t figure out what it is that’s bothering her.

Erika reveals who it is that she’s been trying to reach through social media.

Having topped his grade in the term exams, Nagi confesses to Hiro once again.

The household visits the diner to attend Yohei's birthday party and learn some family secrets surrounding them. The next day after a study session, Erika succumbs to a cold that she caught, and the household, including Hiro, scrambles to help her through it.
