Modern AU set in present-day Mondstadt and Teyvat. Kaeya and Y/N are second-year university students studying at the same university. Both are top-ranking students competing for first place academically while also serving on the student council. They are also both members of the university volleyball club and are well-known on campus for being talented, charismatic, and frustratingly competitive with one another. Their constant rivalry, sharp banter, and inability to back down from challenges make them the center of attention among students. What will bring this amusing rivalry?
