The romance rumor between NCT's Mark and Oh My Girl's Arin ended with a happening.

On Feb 6th, Mark's agency, SM Entertainment dismissed the rumor, saying it was "groundless" to News 1 about their romantic relationship.

The dating rumor began with a photo posted by Arin and Mark on social media accounts.

Rumors of a romantic relationship between the two were raised because the composition of the photo posted by Mark in October last year and the composition of the travel photo posted by Arin on the 5th were similar.

As such, rumors of their romantic relationship, which began with photos of social network services, ended in a simple happening as both sides denied it.
