I can't decide if Eijun or Haruichi would change their names if they ever got married
And if they did, who would take whose name ?
I think Haruichi still has a little bit of that innocent love and fantasies he had about Eijun when he was younger, thinking about changing his last name to Sawamura and growing old together.
But I also think about Eijun being Eijun and wanting to take Haruichi's last name so he can be a Kominato too just because he thinks Haruichi and his brother are so cool and he wants to be cool like that (and probably also influenced by romance stories in some way).
