This occurred on Chapter 194 when The Number decided to meet 001 or Ijin's grandfather

You were a part of The Camp being one of The Numbers being the Number 000, the very first Number in the camp. You, 002, 004, Maya (005), Liam (006), 008, 016, 018, and 032 were at the door of Yu Kangsu (Ijin's grandfather). 032 would ring the doorbell for Dayeon (Ijin's younger sister) opened the door

Dayeon: Oh! It's you... She said covering her mouth

032: heh... Hey.

After going inside everyone sat down in the living room... It was very cramped... 016, Maya, Liam, and 032 sat together shoulder to shoulder and on the other side 002, 008, and 004 sat shoulder to shoulder... Due to 008's large builder he was pushing 004 to the window

Kangsu: i see we've got a big boy in the group!

004: I TOLD YOU TO STOP GETTING BIGGER! BUT NOOOOO. YOU JUST HAD TO KEEP BUILDING UP THOSE MUSCLES!

Dayeon: it looks like the living room might be too small. How about some sit at the table I'll set up the plates.

Maya and 002 got up and sat at the table

Maya: thanks for preparing this for us.

Dayeon: not at all.

Maya: it's fine this is more than enough. She said smiling at Dayeon before looking at 002 with a glare hey! Don't you have something to say to her?

002: after a long pause ...thanks.
