Now moving onto Yano he had begun to have money problems since he had to find a place for his dog and his moms health wasn't great at the time so he had kept this away from Nanami so she could focus on her life and studies. It starts of with Nanami not being able to get into the college that so desired and she had not seen Yano since the train station so she had decided to date his best-friend Takeuchi instead which BIG PLOT TWIST Takeuchi had seen Yano before he had cut ties with all of his old friends. So what I had gathered from the explanation and a little of the manga is that the boy, Yano has had a hard time from moving on from his past dead lover that also had the same name as the current alive Nanami. During this whole time, Yamamoto Yuri has not given up on him. He has since started dating many girls, but states that he "does not treat girls like anything important" anymore.

Yano's personality appears to undergo a change. This too, was not told to Nanami until she was 21 years old. Roughly half a year later, he made a phone call to Nanami's house which was then picked up by her mother.

Yano seems to believe that it was his fault that his mother committed suicide, stating that 'I was the one who killed her'. It is shown that he did see Takeuchi around this time, telling the him that he is leaving Nanami in his care, and that he has decided to give up everything from his past, even those dearest to him. Since the funeral, it is stated that Yano 'completely vanished'. But, after a while, the strings inside Yano's Mother broke and she took her own life (this was taking place half a year of Yano's departure). He also attempted to go to Hokkaido so that he can see Nanami, but in the end he couldn't because of his Mother. Yano kept all of this a secret hoping that Nanami can concentrate on her studies. His mother's health deteriorates both mentally and physically (especially after Yano's dead father's wife shows up with the incline to take Yano back with her). It turns out that ever since moving into Tokyo, Yano ran into a lot of problems such as financial difficulties, finding a place for his dog, Lalami to live in (thanks to a close classmate who later falls for him and even meets Nanami in the company they work at), and his mother's health problems.
