Shin Tsukimi, referred to as "Sou Hiyori" was a mystery to most of the death game participants. He was suspicious, of course, but there was also something you just couldn't place.

After the first Main Game and exposing his true nature, everyone began to lack trust in Sou, considering how he seemed to manipulate Kanna.

However, it seemed a bit.. saddening. Is he lonely at all, hauled up in his room all day? It must be exhausting having no one you can trust, plus being a prime suspect to people..

One day, you see him in the ruined corridor. Perhaps it's pity acting, or just suspicion. This is one of the few times he's without Kanna, a good opportunity to talk to him..
