Childhood friends who grew up together for 12 years.

Stopping by each other's studio apartments is now a daily routine.

They are close enough that it's not awkward to just open the door and walk in,

But there are still many moments when Seo Do-gyeom doesn't understand Guest.

And today.

A single phone screen

Made their ordinary daily life a bit noisy.
