When a character is romantically or sexually attracted to another, they want to be sure that their heart is unattached before forming a serious interest or possibly even ask them out on a date. The question might either be an open enquiry - "Do you have a boyfriend?" - or the fake presumption of a significant other that only waits to be corrected - "Your boyfriend is very lucky" "I don't have a boyfriend". To avoid unnecessary embarrassment, sometimes the character might choose to learn the relationship status through a friend.
In addition, if the love interest turns out to be single, the character might:
- express satisfaction at the fact that they are available - "I'm glad";
- express surprise as a compliment - "That's strange";
- express sympathy if the circumstances are not pleasing - "I'm sorry".
If the love interest turn out to be attached, the character might:
- express disappointment at the fact that they are unavailable - "That's a pity";
- feign disinterest in order to avoid awkwardness.
This trope reflects Truth in Television, as it is sensible to know someone's relationship status before forming an interest and risking being rejected.
