Here’s an idea I have for a first couple chapters of a light novel.
A nice protagonist comes across this big, intimidating female tomboy gyaru. She runs the school with an iron fist. After he bumps into her, she feels she has to protect her reputation, so she tells the MC to meet her in the school playground so she can hit him. Intimidated, the MC accepts.
However, when they get to the school playground, things start to unravel for the tomboy gyaru. Every time time she goes to hit him, things don’t go as planned. First, her mother calls her (She first tells her she’s busy but then ends the conversation quietly saying “I love you too.”) Then, she starts coughing uncontrollably and sneezes 8 times in succession. It’s revealed it’s because she uses the same tissue for multiple days without changing, which she insists is because tissues are a luxury at her house. Finally, as she goes to punch MC, she trips and falls flat on her face on the concrete. Her shoelaces weren’t tied. MC asks if she’s okay, to which the tomboy says “Yeah. I just broke my fall with my face. No biggie.”
Later on, MC takes the school bully to the nurse’s office. There, he asks her how come she considers tissue a luxury. She explains that even though her family makes 93% more than most people, her mother spends it all on bills, alcohol, and cigarettes, with little money left over for other stuff. MC then asks if she thought about applying for a job, to which she says she has, but that they’ve told her her face isn’t customer friendly.
From there, MC proposes a plan: in exchange for bumping into her and making her look foolish, he will help her become healthier and pick up better habits. That way, they will be even steven.
And that sets up the rest of the series.
