I really don't know how to categorize this drama , don't know what to say ... bad? good? weird? Even don't know why keep watching this
At first expecting more epic but ...
I think he did not because other then meet with young , jin sung and hee sun talked about going to see soo and bring him flower reminded him young . When young went to cafe and sat down she touched that flowers.That means jin sung and hee sun went to see him too. So I believe soo is alive. Jin sung seems down because he felt guilty about soo not because he killed him.
Thats what I believe.
