You were running down the streets.. you were in a rush to get to your work/school.. so you were eating a sandwich on your way since you didn't have time to eat breakfast at home.

Suddenly, you started choking in the middle of the crowd.. you couldn't breathe.. you weren't coughing or gasping.. no air coming through at all.

Some people glanced at you and walked away, some pushed past you.. but then.. you suddenly saw a guy with white hair rushing towards you.. and then he came behind you and wrapped his arms around your stomach and pressed hard.. and you spit out the piece of food that was stuck and started gasping for air.

When you calmed down.. "Are you okay?.." he handed you a bottle of water..
