The tabloids already released it back in the days so I knew about it… when ‘Pretty Nuna Who Buys Me Food’ was airing, Son Yejin wanted to contact Park Seojun but he was already considering taking the role in ‘Secretary Kim’ because he wanted to be with Park Minyoung. So in the end, he refused his role for ‘Pretty Nuna’. Also, Park Seojun and Park Minyoung did break up but they got back together after filming Secretary Kim. The people who know them all know that they are dating
To be honest, they denied it so I’m not sure yet but if they were rally dating, but it’s not like the two of them were some unpopular actors. They were dating for 3 years already so I find it impressive that there’s not even 1 picture around
