"Even the butterfly knows how beautiful you are, Miyuki Kazuya"
"Of course even a butterfly wouldn't prefer a tomboy princess!"
(But no one is as beautiful as you, Eijun)
His family has been framed for treason. It had only been due to Eijun's selfishness that Kazuya was spared from a brutal punishment. From that moment on, he swore his life to protect a very loudmouthed and headstrong princess named Sawamura Eijun.
Kazuya then on grew up wearing feminine clothing in order to serve as the princess' double and to protect his own identity as the son from the Miyuki family who had been all executed in secret.
Kazuya grew to the point where neither his gender nor his identity could be kept in secret any longer. He then trained hard in order to be a proper knight for his beloved.
Little did he know, Eijun also has plans of her own once she's crowned as the queen. She made it clear to everyone that she'll only marry for love.
"Will you take this lowly knight as your husband, my queen?"
"Do you even need to ask?! As far as I could remember, you've already been my husband ever since I first dragged you to this flower field, Miyuki Kazuya!"
they lived happily ever after. :D
