You say you like someone else's wife, and it sounds very inappropriate, right? But if you phrase it differently: the person you like has become someone else's wife, and it immediately seems very romantic. A female college student studies during the day and works at a KTV at night, and others might think she's very irresponsible. But if you say she works at a KTV at night and still insists on studying during the day, others will think she's very hardworking. Repeated failures will make her seem very incompetent.
