Both of them are action/thriller dramas with a bit of romance, and both of the plots revolve around a mystery about a military incident, corrupted politicians hiding the truth and secret parent identities.

Both shows are very quick-paced stories about power struggle.
Both have the same Chinese setting: a young scholar arrives to the capital, two princes are trying to get him to their side, each fighting for power. There are also a vile emperor who had came to power by force many years ago with the help of his friends; the local special service and its insidious head, one of those very friends; empress-grandmother, keeper of family secrets; emperor's sister with an illegitimate child...
All these characters have complicated relationship in both shows . But the MLs differ absolutely. JoL is not so serious as NiF, it is full of humour and the ML of JoL is not supersmart. (Moreover, he is sometimes saved by others. )
In JoL we also still don't know what girl the ML is going to prefer so we are waiting for the 2ns season.

Both drama are about a man who truly loved himself, didn't think they fit for marriage & also self-centred.
