Head Over Heels

Eva's life is peaceful, but everything goes awry when she falls in love with Keij. A man of stone at heart, a man who ignores women around him. She chased the young man, but he drove her away. Now the card was reversed, he's now chasing after her.
Eventually, they became a couple, but one mistake broke them apart. One big mistake.
One night made her life miserable.

"I'll accept your offer, it's excellent. But there's missing."
"What do you want, sir?"
"Be my bride."
Will Eva be willing to marry him?
