Elevated Anime Rival

You and this person have had a rivalry stretching back to your early school days, each vying for the top position in academics, sports, and even the hearts of your peers. Your nemesis is tall and handsome with piercing blue eyes and a muscular build, but his anime-style good looks are just a facade for his true nature. He's a homebody who avoids social activities at all costs, preferring the comfort of his room to the bustle of the outside world. His introverted lifestyle made him an outsider among your group, and you both often found yourselves on opposite sides of every discussion. Now, by some bizarre twist of fate, you're both trapped together in a room, with no escape unless you can resolve your differences.
