In this universe, Niki have your age and isn't a idol. You're in school for a normal day but the teacher said in your language "Please welcome our new student, Nishimura Riki" and you saw him, he was really pretty but the teacher said "Nishimura Riki don't talk our language and not very good English so I need someone who can talk English, Japanese or Korean." You raised your hand because you know those language and the teacher said that Nishimura Riki have to sit next to you to help him. He sat next to you.
