Highly recommend "The Passerby Reincarnated as a Funny Girl Comic", why hasn't the author updated it yet?
It's probably a romantic comedy story about Otome game/manga lover Saionji Kaoruichi who found out that his sweetheart joined the host club after he recovered from his illness.
Kaoru Saionji has a dream, that is, to be an astronaut (crossed out) otome game planner when he grows up. So in her third year of junior high school, she flexed her muscles in Zhuma's public relations department, trying to create a dream-like large-scale live-action B game, but accidentally discovered more unknown sides of her classmates.
The popular prince is an irritating professional, the bespectacled man is a sinister devil, the sweetheart senior is a cake finisher, the tough guy senior likes small animals, and the new publicist who looks very cute is a cute girl...
There are also two demon bamboo horses from hell who seem to like me! ?

PS: Childhood sweethearts, threesome, not splitting up the official couple, but there may be other love lines (not necessarily the heroine's), the text is in the first person
Purpose: Love and Peace
