The comic is about a young lady who was on her way to hometown. There were few people on the bus, around ten people. She was reading her book so she could get away from boredom since it's a long trip. Yongin-si doesn't have a plain terrain so there are a lot of tunnels on the city. When the bus went through Ma-sung tunnel, she couldn't read more because, obviously, it was too dark, so she took a nap. When she woke up, she noticed that the bus was still on the tunnel, and a few minutes, she noticed that the tunnel was a never ending ride.
