Busu ni Hanataba wo.

From Yen Press: Hana Tabata has accepted her role as the unattractive side character in other people’s stories. Though her name is Japanese for “flower,” she sure doesn’t feel like one. That doesn’t mean she can’t enjoy some heart-pounding romance manga and maybe occasionally, every so often, imagine herself as the heroine. But when the most popular guy in class stumbles upon a daydreaming Hana, she braces herself for the embarrassment and humiliation to come. Unexpectedly, he keeps her secret and he also won’t stop striking up conversations with her! Ever the pessimist, Hana can’t help feeling suspicious. But could it be that his friendly demeanor is genuine? New 5 chapters, under the subtitle Bloom, were released in 2025 to promote the anime and collected as Vol 13.
