When the cherry blossom fades

If there is one thing people expect out of an alliance, it is peace.

No one expects conflicts to heighten or wars to break out. No one expects buried secrets to come to light or hidden agendas to be exposed.

So what triggered it all? Was it the Seventh Prince, the King of Jeontu, the Emperor of Shangwei, their minister, or someone neither of them expected? Will peace ever result? If so, who will restore it?

Who's tragic back story is going to cause havoc to the nations as two young lovers learn to trust one another?

"Aeng-ah, please repeat after me. 'I will not cause any trouble for Jeontu, Shangwei, and especially your husband.' Please keep to those words."

"Your Highness, other than you I don't necessarily have a goal. So please stop threatening me already. Put down the Bao bao, let us have a heart-to-heart." Han Aeng thought for a bit, before continuing, "You can trust me."

Long Dahai's heart wanted to trust her words, but her eyes were murky - as clear as a muddy river. It made him think of all the times she'd proven otherwise. "Quite frankly, I don't trust the way you said I can trust you."

"Oh, come on! I'm the suspicious one!? Are you all going to ignore the dude running around in a black suit, laughing like a lunatic?!"

"...I'll take my chances."
