This is basically the Teyvat people are reacting to different stories and eventsnwith the main focus of different version of Aether and his quests. (First two acts will be story quest of Zhongli and Venti. after will different version of Aether with different pairings) (Aether harem)

Alexei Ivey is a shy and sweet twenty five year old who has been working at Armas Marketing for a year. He is a sub who knows what he wants. And what he wants, is a man whom he wholeheartedly wanted to belong to. A relationship. Malakai Armas is strong willed, smart and the CEO of Armas Marketing. At work, he is cold, renitent and as a dom, he is nothing short of respectful and perfect. It takes one trip in the employee's elevator for him to notice Alexei and it takes him hours, wondering just how he had never noticed such a beautiful boy. Malakai knows what he wants and how to get it. And what he wants is Alexei Ivey on his knees, his hands tied behind his back and big blue eyes looking up at him.
