Detective duo dynamic, intricate and thrilling plot. The leads bicker at first but work off of each other's strengths and learn from one another.

office/corporate settings in both
Chemistry hot in both.. only in FITYMI, there's banter between people of same status/value and ego.. in the early spring,for now,FL feels inferior.
And life lessons mostly is very present in FITYMI (there's a little in the early spring)

If you're hungry for another enormous historical canvas, this is the kind of thing I'd investigate next: dynastic politics, military campaigns and the formation of an empire rather than romance-first storytelling.

?? Romance: Low
? Emotional intensity: Emotional
? Tropes: Empire building • Warfare • Political struggle • Historical figures • Succession

If the wronged heroine + revenge + powerful allies aspect of Road to Splendor was your favorite, this one will hook you quickly. It's considerably more revenge-driven.
?? Romance: High
? Emotional Intensity: High
? Shared Tropes: Wronged heroine, second chance, revenge, political intrigue, dangerous ML

If you want more mature romance + political/military intrigue, go here. The leads become partners rather than simply a romance happening around the plot.

Dynamic is similar, one part of the pairing is quite manipulative and is seeking revenge due to circumstances, their partner has a different moral compass than them and works to talk them out of revenge at some point in the story. As a side note, there’s a body guard and employer side couple

Both workplace romance- superior/subordinate. ML's are very much interested and pursue FL pretty early on (not one-sided tho). Both dramas they reunite later on after initial romance. Also both fast-pace.

Both have same main female leads. Beginning of Moonlight refers to/shows ending clip from A Familiar Stranger about the two FLs, who meet again in Moonlight.
