Light (2021)

Started off with a fake marriage. FL marries in order to find out the murder of her father. She purposely gets close to the ML to get closer the his boss.

Set at the same time, in the same era of Republican China, and have a similar theme of bloodshed. Gives revolutionary vibes for both. Both have the spy aspect to them.

Both tell a story about a humble intellectual's journey to become a great financial and banker.
Zhang Xincheng performance in The Justice was so awesome that in my opinion, he single handed-ly supported the drama.
You may like the light romance in War of Faith more than the frustrating fml in The Justice.
Romance aside, both drama were truly enjoyable.
++(imo) The Justice have more clear script and plot that it',s easier to follow and understood compared to War of Faith. When Wang Yi Bo's performance in WoF is undeniable outstanding, but we have Zhang XinCheng here. If you like WoF and have lingering feeling while waiting for next episode, The Justice is a good to kill the time.

-Both are republican drama
-Both have smart FL
-FL tried to get closer to ML with a bad purpose
-Both have a love-hate relationship story
-Both have the same main plot. It's about revenge
