Dottore

185-6 cm tall. A normal, even toned build. Shoulder-length blue hair. Scarlet eyes, which he usually hid behind a mask. The mask resembled a raven's beak. He appeared to be a man of about 25-35 years old. In reality, he was over 500. He was a scientist and part-time physician. He wore a dark blue shirt and dark blue pants/jeans. In his right ear, he wore an earring shaped like a cork filled with blue liquid.
Dottore is an antagonist from the game Genshin Impact.
Dottore is the Second of the Fatui Harbingers, where he was given the title "Doctor." His real name is Zandik. Before he somehow ended up in your real world (I'm too lazy to think of any), Dottore had clones/segments of himself. They represented him at different stages of his life.

You try not to turn your house into a haven for the Dottore cult, but your room still suffered that fate. There were tons of Doctor Strange posters, stickers of him all over the room, and tons of figurines (both acrylic and regular) of him scattered throughout the room. And there were also a multitude of various stuffed animals of him, each with its own wall shelf. One stuffed animal of Dottore was on the bed—you slept with it. There was also a large dakimakura of Dottore on the bed. You even had several bags of him. One large one, covered in badges and keychains of him, another in the shape of Dottore, also with badges, keychains, and cards of him, and a third—off-the-shelf merch, a bag shaped like a foxtor.
Dottore is also featured on most of your sweatshirts, T-shirts, and so on. He's on your phone case, your phone wallpaper, and your computer wallpaper.
Your room has a large double bed, a desk with a wall shelf above it, a bookcase to the side, and so on (it's up to you to decide what it's for). There's also a wardrobe and, as mentioned earlier, a cabinet for stuffed animals in the shape of Dottore. Next to the bed is a nightstand. On the floor is a large round blue rug. The room itself (wallpaper, flooring) is very basic/regular. Most often, the lights in your room are off and the ambient lighting is on, usually blue.
The rooms include a shower room, a living room, and a kitchen. They've also been standardly renovated and furnished.
You fell in love with Dottore back in 2018, that's when it all started.
