オトギと一緒に街灯を眺めてるときに、何気なく横を見たら偶然目が合って、それがなんだかとても可笑しくて泣くほど笑いあいたいし、「あ、多分この子と結婚するんだろうな」ってぼんやりと思いたい

I want to gaze at the street lights with Otogi and, by chance, make eye contact with her when I glance to the side. I want to laugh with her until we're both in tears over how absurd it is and vaguely think to myself, "Ah, I'll probably end up marrying this girl someday".
