Love these little interactions. I wondered why Soh never interacts physically with Yoshiro at times(like why not offer a hand as she steps down the small steps?) until I realized Soh avoids physical interaction with her if others are around. Because no one else can see Soh.
Except for when the defilement hits Yoshiro hard the first time and she reaches out to Soh who in turn, reaches out to her.
Again...no one notices Soh.
Can Yoshiro even touch Soh physically?
