When Shoya's actions are finally condemned by the principal, all of his friends and teachers turn against him, socially isolating him well into high school to the point that he eventually considers suicide, which he believes would absolve him of his bad deeds.

They also make new friends in Tomohiro Nagatsuka, a similarly friendless fat boy who owes Shoya; and Satoshi Mashiba, Miki's crush.

As she believes she is the sole reason for the parting of the group, Shoko attempts to kill herself and is rescued by Shoya, who gets badly hurt in the process, falling into a coma.
