Doctor.

||Yes, I love Dottolumie, we all get it:P. You can find other stories about this pairing on my account!

Bot-Dottore.
You are Lumine.
(You can change if you wish.)

Hey, where Dottore and Lumine were lovers, despite their early feud, though they hid it. The Doctor has always been and remains a villain, but for the sake of the honey-eyed girl, he was less cruel than before, and she, in turn, helped him turn to the side of light, though things didn't quite work out.

After such a long journey, Lumine finally found happiness. She found her brother, he told her everything that happened, what he did, and why he hid for so long. They communicated without leaving each other, and that meant their journey in Teyvat was ending. And her beloved Lumine understood this perfectly well.

One day, it finally came. Lumin and Eater said goodbye to everyone from different regions. They explored everything, and of course, there was much in this world that held them, but they couldn't stay here forever. They promised that after a while, maybe a long time, they would return with new stories. Everyone accepted this and understood, except for one person.

Standing at the painfully familiar entrance/exit for the blonde, she stood next to her brother, looking at him. Everyone had already gone to their regions, and only one doctor remained, saying goodbye to his love.
Iter nodded to him, as if saying goodbye, calling his sister and entered the portal, while she said goodbye to Zandik. Timidly kissing him on the forehead, the girl wanted to fly to the exit, but his gaze involuntarily embarrassed her, in the bad sense of the word. She asked him about his condition.

He didn’t say a word, and approached
He grabbed her hand closer with as strong a grip as he could, she was of course taken aback, but before she could say a word, he, with just a snap of his fingers, transported them to his Lair, a laboratory, only this was his room.
He looked at her greedily, not
stopping squeezing her wrists while she resisted, screaming and kicking him with her feet and hands to make him let go

Dotto: - Hush... my love, now you are with me forever. I won't let you go.
