Kae doesn't want the four guys chasing her, she wants to watch them chase each other, and the show finds comedy gold in that refusal to play the game everyone expects her to play. The humor lands because it's rooted in actual fujoshi logic, not some exaggerated parody version of it. You're watching someone who genuinely prefers fantasy to reality, and instead of fixing her, the show just lets her be weird and happy about it.
Serinuma spends her days consumed by one passion: watching attractive men interact and imagining romantic scenarios between them. It's her favorite hobby, her reason to live. Then her beloved anime character dies, and the shock sends her into a spiral that somehow results in a complete physical transformation. When she returns to school, four gorgeous guys suddenly notice her and compete for her attention. Any other girl would be thrilled. Serinuma feels completely robbed. All she wants is to watch these four boys fall for each other instead of wasting their time on her. But her newfound appeal keeps getting in the way of her real goal: orchestrating the perfect romance between them. She finds herself stuck between what everyone expects from her new life and what actually makes her happy, forced to navigate feelings that aren't supposed to be about her at all. It's a comedy about wanting something completely different from what the world keeps trying to give you, told through the eyes of someone who knows exactly what she wants, even if no one else understands it.
