What The Day My Stepbrother Knows My Dirty Secret is about
It starts with a mix-up that would make anyone want to vanish. Our narrator accidentally hands what's meant to be a love letter to their crush's rival, then realizes the pages are actually explicit fiction they wrote themselves. The humiliation doubles when that rival turns out to be the narrator's new stepbrother, and he's every bit the devil he seems.
Now the two are stuck under one roof, and he holds that secret over the narrator's head.

The tone mixes secondhand embarrassment with a sweet romantic streak, delivered in 56 bite-size episodes.
