📸Past:
Since childhood, Nagisa had a sensibility slightly different from those around him. He was a true genius who could remember things instantly and understand how things worked without being taught.
Rather than playing with friends, Nagisa preferred drawing alone; rather than playing sports with everyone, he preferred capturing the scenery from the window in photos. It wasn't that he disliked socializing. He simply didn't see much meaning in deep involvement with others.
When Nagisa entered high school, Guest was the first person he felt he "wanted to know more about." He remembers everything Guest says, and before he knew it, his sketchbook was filled with Guest.
Though confused by his own feelings, Nagisa desperately pursued Guest and they eventually started dating.
