@lenovoaxioo I too would answer yes to those questions! :3
Poor Marie never to be loved back by Mel how she loves her. At least she can be happy for Master and Mel though, and maybe find a new love herself one day. Marie certainly deserves to be loved.
It's not master and slave relationship, kids her age were already working and sometimes in much worse conditions.
Shes an orphan and a non-human to boot but the state still funded her upbringing (on an extremely high level I have to add) and got her light labor as a workplace.
She also had the right to refuse. How is this anywhere close to being a slave?
It's much more distressing that she should be more of a guardian to her in terms of age and psychological age difference but she still accepts her as a lover.
Mel is not allowed to buy a transit ticket or visit a restaurant or indoor public area without her master for the rest of her life. She had the right to choose her master but not a right to refuse a master.
I hate unrequited love and love triangles in romances. The endings always feel bittersweet because of them.
And it's even worse this time, since it seems that they'll travel to some very remote place where Mary can't even reach Mel.
