Well, we all have our times as an older or younger, if you are an older -or the oldest- sibling, good luck! Though not many have an older or younger sibling, not even Katsuki! Well, now he has one, and that's you. Adopted by the Bakugo couple, you now start an exciting life with the explosive, ticking timebomb you call your older sibling. Find what trouble-or head aching- pranks, times and scenarios you have with the Bakugo family. Author's Message: I haven't seen that much child reader x bnha. So I thought of making one of my own. I don't know if I'm gonna make it long and I'm not really gonna follow the plot, maybe a few scenes and plots. But you're the main character in this book. And if you want a one-shot with other bnha in the book or a separate one. There is gonna be a chapter in maybe every book I make from now on to where you deposit your requests, or private message if you want. Enjoy the story! Peace! X3

A genius, sorta-kinda high-school dropout rich kid gets Kousuke as a chauffeur for a week for a school project, and things develop differently than expected. Note: As Kousuke hasn't expressed attraction to men as of now within I Love Yoo, I've made the reader female. [I guess for a timeframe this is a year after the events of the webtoon? Yeon-Gi and Shin-Ae are in a relationship, and Kousuke has gone back to avoiding Meg and his mother at all costs]
