"What do you need me to do?" Shingo asked after a period of contemplative silence.
"Please pay attention to anything strange that may happen to or around you. Also, please contact me immediately if anything strange does happen. Or, you can contact Chiaki."

"…That's all?"
"That's all."
"You don't want any money?"
"I don't need money."
Shingo took a deep look at the boy sitting across from him and then retracted his gaze.
"Let's do things like that, then." After saying that, he stood up again.
"Dad…" When Chiaki saw this, she couldn't help but call out to him.
