Ah, we can all speculate. I hope she's smarter than the usual FL and won't just stand there accusing him. It looks like abandoning her as a protective thing backfired.
Are you talking about Duke Xu backstory? This is a very commun plot in my historical c-dramas, some just use it…
Fang Fei would not be as funny as Shao Shang and Duke Su would never be interested in Shao Shang's savvy but uneducated innocence. Fang Fei would eat all the Princesses of LLTG for breakfast and Ling Bu Yi would kill everybody by the 20th episode, LMAO. But all four would jump off the cliff just for fun.
watch the extra ep, the ML doesn't die, he lives happily with the FML, though his subordinates do die
I do agree about the subs dying. I always end my rewatching at Episode 40 around the 33 minute nark, right at the wedding. They kiss and fade out. The end.
