Proditone. Onero. Lux. Obduro.

(also abbreviated to POLO) a popular fanfic on AO3 within the SMZS fandom written by users enigma3000 and mehan kartik (daydreaming story teller).

This fic depicts the main characters of SMZS in an action packed Spy AU with Kartik Singh being a spy and Aman Tripathi as his husband who is slowly coming to the realisation that his husband may not be as he seems. The fic, already gut-wrenching despite the author's protestations otherwise, takes your typical stereotypical spy romance plot and made it into a absolutely thrilling action/mystery fix with a beautiful blend of humour and angst.

Fans of this fic are particularly fond of bars and Polo candies. Though it is yet unclear why the fic's abbreviation is POLO specifically.

The fic has been hyped up ever since its embryonic stage and when the first update aired, it gained strong positive fanbase who are eagerly awaiting the next instalments of this fic.
