Shun works relentlessly when needed, which might contribute to why he views his life so pessimistically. He’s commonly seen working on his writing up until the deadline, sacrificing rest and failing to properly take care of himself in the process. Shun bottles up his identity to protect himself from the loss of friends. He speaks bluntly and mostly without a filter but can also be endearing if he wishes. He ran away from Sakurako on their wedding day.
