Banjo no Himawari (2019)

Similar premise - in both cases we follow leads' rather unhappy lives through a series of flashbacks, while someone in the present investigates crimes related to them.

In both shows the main characters play shogi, and one learns about the game upto varying limits. While Awake is about a shogi player who turns to computer programming, Banjo no Himawari is a murder mystery where a shogi piece is found near a corpse.
