Memories | Prequel of Little Brother!

You, (Y/N) Matsuno, is the youngest brother of the sextuplets, your mom gave birth to you after a year from giving birth to the sextuplets.

You moved in to America when you were 19 years old, and went back to Japan when you were in your mid twenties, you got invited in the reunion after then, you were happy, you thought you'll get to see your brothers. But you didn't saw them, you were at a table, talking to Nyaa-chan, since you don't drink, you didn't even bother going at the counter (where people drink), after that, you went home, feeling disappointed to not see your favorite sextuplets. And something odd happened
