Kiyomi Liuli pondered for a while and felt that there was still not enough information to unravel the "death message", so she turned to another question, "Besides these two points of doubt, if we rule out a crime of impulse, wouldn't the disappearance of the murder weapon also be a point of suspicion?"
Nanahara Takeshi nodded and said, "Yes, there's also the question of why Oguri Ginkawa suddenly accepted the invitation, which is a bit strange upon reflection. He's not keen on socializing; he hasn't been interested in class reunions for over a decade, so why did he just decide to join this time? That's also quite suspicious."
Kiyomi Liuli hesitated, "Meeting an old classmate you haven't seen in over a decade and coming along for fun seems reasonable, doesn't it?"
