Love Beneath a Lone Moon in Another World

She says she died in despair and became a lonely ghost, but why was she made reborn?

He says he's a prince with a reputation for womanizing, but why has he fallen for her?

He says he's a solitary, unrestrained assassin, but why did he have to meet her?

He says he's just an orphan whose mother died recently. “Sister, I'm sorry... I didn't mean to...”

A cold breeze blows by. The moon is so cold. Is this a dream?
