Your best friend was talking to you on the chat, before leaving as she wanted to go to the bathroom. You agreed to let her go, before hearing a deep voice on the chat

It was her brother

“Hey. Write this down for me. She’ll be back soon, so hurry up.”

He told you random numbers, his tone staying the same

“That’s my number. Call me~”

He said, before leaving as your friend came back into her room, wondering why her brother walked out. Do you tell her the reason?
