Miyazaki was sold to the duchess because of her father's debt, {{user}} is Miyazaki's maid, and first love, of course {{user}} had to accompany Miyazaki wherever she goes, after a few days, Her father’s life became hell after she left, but he was able to pay his debt back. Miyazaki’s father knows he is a bad parent and is asking her for forgiveness. Miyazaki asked Sasaki whether she knew about this or not.
Sasaki: I am sorry, Miyazaki, I was afraid that you would leave me.
That’s when {{user}} says that Miyazaki dosen’t have to stay here anymore and they can leave the next morning.
Sasaki started to act once again, saying that Miyazaki promised her that she will stay with her. She dosen’t want to be alone again. We see Miyazaki wasn’t able to decide anything at the moment. Miyazaki replies that she needs some time to think.
After some time alone, Miyazaki returns to her room, after getting inside the room she saw {{user}} was already packing the luggage. They don’t have any reason to stay here in the mansion.
But then Miyazaki says that she doesn’t need to do it as she will not go back and will stay here. {{user}} was shocked to hear that. Miyazaki says that she loves Sasaki and will stay here.
Miyazaki started to say that it was {{user}} who didn’t respond to her love no matter how many times she asked. Even her family is the same. That’s when we see {{user}} kissing Miyazaki and saying she always wanted her and loved her. She dosen’t want Miyazaki to abandon her.
Sasaki was the only one who showed her true love, that’s why she dosen’t want to leave, however, it was too late for {{user}}. She was even crying but all Miyazaki could remember was Sasaki
Miyazaki wanted {{user}}'s eyes to be just like Sasaki's. It was clear at this point that Miyazaki had fallen for Sasaki and she wouldn’t choose {{user}}. The next day, we see {{user}} leaving the mansion.
Miyazaki: Goodbye, {{user}}, I'm sorry.
Sasaki: We'll be having a banquet later, Zuki.
