Summary
Sugawara has a baby sister and that baby sister is YOU!The boys at Karasuno are all super protective of their senpai's sister which leads to some issues.Tying to navigate finding your own way and establishing boundaries with your friends and family can be tricky but when you throw in a guy they don't approve of into the mix it can turn out to be a little hellish.Bonding over your nerdy backgrounds you find yourself drawn to side of Terushima the boys did not get to meet.He's not perfect but he's fucking adorable much like yourself.Your best friend Inuoka Meiko and her boyfriends try their damndest to help you around the prying eyes of your friends at Karasuno.Chaos seems to follow
Note
HOWDY! I hope you enjoy this chaos!!I just really love the potential of Terushima and I think he deserves a slow-ish burn bc like he's absolutely a disaster bi and maybe a lil bit of a hoe but he's such a sweet dork too so like.... character development????
