Chuunibyou demo Koi ga Shitai! Ren: The Rikka Wars

During a typical school day, Rikka Takanashi notices Makoto Isshiki secretly passing a flash drive to Yuuta Togashi. Intrigued, Rikka discusses the situation with her friends, who agree that Yuuta is hiding something from her. They decide to uncover the contents of the flash drive by any means necessary. To their surprise, it only contained pictures of an idol that Yuuta adored back in middle school. However, Rikka is offended, claiming this breaks their contract as lovers, and demands Yuuta to return the flash drive. Although she sees Yuuta return the flash drive, she still feels uncertain. This leads her to sneak into Yuuta's room at night, only to discover that the flash drive had not been returned. Scanning through its contents, she hurriedly rushes to bed when Yuuta enters her room. To her horror, she finds the flash drive crushed due to her negligence. Yuuta quickly finds out and demands an apology. However, Rikka also demands an apology from him, resulting in both refusing to apologize first. Will the two lovebirds resolve their argument?
