How to use Rune...

Hikaru was startled upon hearing that, he then saw Narita sitting on the sofa, holding a cup of hot tea.

Hikaru saw Narita return and let out a sigh of relief. Even though he knew that Narita wouldn't run away, he still felt a little nervous in his heart.

Now seeing Narita, Hikaru was completely free of worries.

"You lived in ancient times, right? Could it be that there was no tea when you lived?"

"Ah!" Narita tilted his head: "So this drink is called tea?"
