[R18/18+] Bored out of his mind waiting for his first semester of college to start, Eren resents being stuck babysitting his adopted five-year-old sister while their parents are on vacation. She's a handful, but she's also the best wingman he's ever had. // Inspired by Alice in Wonderland and The Garden of Words. This work was originally posted on Ao3. // Even though this is really fluffy, please be aware that it's still a mature rated fic!
