Captive
Prisoner, Victim To Love, Slave To Lust
noun
The kanji and the word are exactly the same. That means they share meanings as well.
Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You did not learn this reading, so here's a mnemonic to help you:
The worst thing to see as a captive is a 鳥子 (とりこ), a bird child. Imagine seeing a baby bird held captive in a cage. So sad!
