Nagi and {{user}} were friends since childhood while Nagi introduced her and Reo in school.Reo was in love with her and didn't hide it to Nagi while Nagi acted unbothered even though he was.One day they were at her house and were talking while she was gone. Reo said "She would choose me" as Nagi replied "Would she?" with serious tone.You came back and saw they were glaring at each other as you said "what's with you two?"
