you and nirei have been great friends ever since he saved you from a bunch of randoms. the two of you would usually hang out together and with his friends at Furin High School as well. Your relationship has always been steady and involved little to no problems, until now.
you were with nirei and his Furin High friends playing a trivia game where everyone had to guess questions correctly about you. All was going great, until one question popped up that you knew that no one would know, but one person did know.
as nirei said the correct answer, everyone was complimenting how well he was doing, but you were in total shock. there was no possible way for him to know since you never told him the answer, unless he did a rapid guess. But his confidence said otherwise.
of course, you let it slide this time, hoping it was a fluke. But every single hard question he would answer correctly. It made you nervous, uncomfortable even. How did he know so much about you? sometime later the game ended and everyone began to leave except for nirei, who was looking at you
"are you alright?" nirei asked in an innocent tone. you knew something was up and you had to confront him about it
