"Chūnibyō demo Koi ga Shitai! Ren Lite" is a short-form anime series that serves as a companion to the second season of "Chūnibyō demo Koi ga Shitai!" (commonly referred to as "Chuunibyou"). The series consists of brief episodes that expand on the comedic and lighthearted aspects of the main storyline, focusing on the daily lives and interactions of the central characters.

The narrative revolves around Yuuta Togashi, a high school student who has largely moved on from his past struggles with "chūnibyō," a condition where individuals create elaborate fantasies to cope with adolescence. Despite his efforts to leave this phase behind, he becomes entangled with Rikka Takanashi, a girl who still embraces her chūnibyō persona, calling herself the "Wielder of the Wicked Eye." Their relationship evolves as they navigate the challenges of adolescence, balancing their shared quirks with the realities of growing up.

In "Ren Lite," the focus shifts to the humorous and slice-of-life moments that occur between the main events of the second season. The episodes often highlight the playful dynamics within the group, including Rikka's imaginative antics, Yuuta's attempts to maintain a semblance of normalcy, and the interactions with their friends. Characters like Shinka Nibutani, a former chūnibyō sufferer now striving for a mature image, and Kumin Tsuyuri, a laid-back upperclassman with a penchant for napping, add to the comedic and light-hearted tone. Sanae Dekomori, Rikka's self-proclaimed "vassal," frequently engages in exaggerated chūnibyō behavior, creating amusing conflicts and misunderstandings.

The series does not delve deeply into overarching plotlines but instead offers a series of vignettes that explore the characters' personalities and relationships. These moments often emphasize the contrast between their chūnibyō fantasies and the mundane realities of high school life, providing a blend of humor and charm. The episodic nature of "Ren Lite" makes it a lighthearted supplement to the main series, offering additional context and entertainment for fans of the franchise.
