...Yuri entered the facility.

Yuri walked in when Serene was talking to Wayne. During that moment, Yuri checked the people who arrived.
When Serene finished her last sentence, Yuri formed his hand into a fist and put it in front of his mouth, coughing twice.

*Cough* *Cough*

"Sorry to interrupt, but hello! My name is Lakeev, Yuri. I believe that you are from the highway just like me. I think that I might be the last one to come. The mob you mentioned... Those undead cannibals... They are still at the roadblock. Well, most of them are. Ea... Those poor bastards. We still have some time, but, as you mentioned, not much.
Is there a janitors or a maintenance room around here? They could have something we could use."

Yuri tried to be as polite as possible, as the first impression was always the most important. Especially when you need to rely on your new allies.
