孤魂 is a Chinese title that means “lonely soul.”

In the context of being a soul without a mate or all alone, this can be translated as a “lost soul.”

In Chinese, this can mean losing one's love; to breaking up (in a romantic relationship); to feel jilted.

In Japanese Kanji, this means disappointing love, broken heart, unrequited love, or being lovelorn.

失戀 is also valid in old Korean Hanja, which means unrequited love, unreturned love, a disappointment in love, or a broken heart.

Note: In modern Japan, they will tend to write the more simple 失恋 form instead of 失戀. If you order this from the Japanese master calligrapher, expect the more simple modern version to be written (unless you give us instructions to use the older or more traditional version).
