Think, Consider
In a coffin is someone begging. But, it won't work. You won't listen. So, the man in the coffin just begins to think: What could I have done better in my life? Why am I in this situation? How will I get out? Think, damnit, think!!
Imagine him changing from a begging position to a stereotypical "thinking" position, hand on chin, eyebrows furrowed. Focus on the beggar's thinking. This is a pretty abstract idea to imagine, so it will be important to create a very vivid picture in your mind's eye.

What is the beggar thinking of? A thought bubble pops up into existence near his head. In it is a picture of こういち! He's thinking that if こういち was here, he'd save him. Oh, if only こういち could save us all!
Then, the beggar realizes that he is こういち. You're burying こういち in a coffin alive and all he can think of is himself.
