it might well have been for the best that Meiling sunk her own chances at onee-san employment. Sakuya would not have agreed to it and you can't forget to ask her for consent on anything to do with Meiling.
Hmm, this has a similar premise to Fuuzen Lamp's short story, Shoukei no Ori, which also explores dragons and dragon turtles. Pretty much, Yacchie mistaking Meiling for her lost sister. Good read too.
