I have only watched the first 3 episodes of solomon, but, the premise and the story so far is very similar to 3nen a-gumi. Both are fantastic and I highly recommend you give 3nen a-gumi a go if you're enjoying solomon!
In both dramas, the characters questioned themselves abt the death of their friend. Is there someone to blame? Who's really in fault? They only move on with their lives after answering these questions.
