>>32265355from the JP clip, she never picked it up.
Pekora told her hey you dropped this, pick it up.
Koyori saw and stared at it and said "what? a note?" over VC.
Suisei heard it and asked what note.
Pekora then took the note.
Koyori was one of the first to arrive to Peko's base. She approached unarmed step by step, wanting to join Pekora. But Peko spotted her standing on the water and headshotted her. Koyori understood that they were uncommunicated for good.
After everything, fate made Koyo find the note inside peko's base. And remembered the moment she was too slow to pick up the note.
