Volcano Triangle (Passing... Heart Pattern)

Triangle... of Missed Encounters is the seventh episode of the second season of the anime series Chunnibyou Demo Koi ga Shitai. It was broadcast in Japan on February 19, 2014.

Synopsis
Yuuta Togashi and Rikka Takanashi's sightseeing date is interrupted when they come across Satone Shichimiya, who had gotten separated from her own class trip after losing her purse. They manage to help her find it, but Yuuta and Satone end up getting chased by a wild monkey in the process.

When Rikka spots Yuuta receiving an arcade token from Satone, she runs off tearfully feeling Yuuta had betrayed her, eventually coming across Shinka. As Yuuta goes to search for her, Satone calls Kuzuha Togashi up, before calling Rikka to meet up with her so they can talk. Satone explains that she once fell in love with Yuuta, but threw her feelings away to hold onto her chuunibyou identity, leaving Rikka with the question of whether she intends to keep her identity forever and revive Yuuta's.

After Satone takes her leave, Yuuta reunites with Rikka and gives her a new umbrella and charm for her birthday, prompting Rikka to say "I love you."

Meanwhile, Sanae Dekomori  finds a note in her bag, presumably secreted there by Natsumi Tokugawa. It has a link to the new Mori Summer website. Dekomori messages the website admin to find out if they could be the real Mori Summer whom Dekomori has been looking for.
