Things are changing quickly for Yoshida, as the girls at work start to take an interest in him. Meanwhile, he tries to get Sayu a cellphone, but she refuses…

Yoshida settles into his new life with Sayu, but the people around him are quick to notice the change, and very curious about what's going on.

Sayu picks up a part-time job, which leads her to make a new friend. The new friend wants to come over, but what if she finds about Sayu and Yoshida?

Gotou demands to be taken to see Sayu. Is she trying to get a love rival out of the picture, or is she after something else?

Sayu has an encounter with a man from her recent past, and his intentions aren't good at all.

As Sayu's family gets closer and closer to tracking her down, she realizes that she may be heading home sooner than she thinks.

Sayu's brother has tracked her down, and she realizes it's only a matter of time before she has to go home. She's forced to reflect; what did she learn since she ran away, and what will she take home with her?

Before she goes home, Sayu decides to open up about her terrible past, and what made her run away.

As Sayu prepares to go home, Yoshida is forced to make a choice. Will he let their relationship end here?

Yoshida follows Sayu back to Hokkaido, as she begins to face her past and come to terms with her future.

Back in Hokkaido, Sayu returns home to confront her mom and decide her future.

It's time for Yoshida to head back home, and Sayu to return to her old life. Can she get by without him, and can he get by without her?
