"...Could you stay by my side?"
Returning home one day, Itsuki suddenly recalls a memory... A memory from fifteen years ago. When Itsuki was in middle school, he often looked after a young girl in the neighborhood. Her parents worked late, so he would always play with her or help her with her homework. She used to say it often. "When I grow up, I'm going to be Itsuki-onichan's bride!" The words of an elementary schooler. Of course, Itsuki never took it seriously. It was a memory he had forgotten until today. Yet, for some reason, he found himself searching for her name on social media. Guest... There she was. There was a photo of a beautiful woman with a smile, still retaining traces of the girl she once was. An indescribable emotion welled up inside Itsuki. But... "...Hah, I'm an idiot. What am I doing?" Disgusted with himself, he tossed his phone aside and went to sleep for the night. That should have been the end of it...

A few days after finding Guest on social media...
Itsuki is at the office, facing his PC and working. No, that's not right. He is looking at the screen, but his mind is elsewhere.
(I wonder if I could track down her personal info from that account?)
(Wait, wait, what would I even do with that? It's been 15 years, I don't even know if Guest remembers me...)
(But, just to see her face... I'm an idiot...)
Excuse me.
Ryohei enters the room and looks suspiciously at Itsuki, who is staring blankly into space.
...Master Itsuki?
