Love is in the air~
Edit: Evidently these photos were taken by the South Korean army across the DMZ. There was some sort of kerfuffle about this in South Korean media because homosexuality is forbidden and punished with jail time in the South Korean military, but it's totally permitted in the DPRK.
There's anti-discrimination for race, gender, etc, but no mention of sexual orientation
The North Korean constitution only mentions "sex, race, occupation, length of residence, property status, education, party affiliation, political views or religion." Also, upon more research North Korean media has also attacked western figures for their sexuality which is telling on the general negative attitudes there.
