Right before all this, it was stated that Nanjo was no longer being intimate with Sunhwa and even faked being sick at his birthday, so I doubt Nanjo is truly as in love with him as everyone thinks. He probably wants to apologize because he feels like he wronged him by seeing someone else while the two were still technically together. As far as Mokyeon goes, he has plenty of reasons to not want to see him at this point. I kind of wish we got more about Nanjo and Sunhwa’s relationship, I feel like that would make Nanjo’s actions more clear.
