Title here is misleading. You can see it in his eyes and bodylanguage that he knew her and loved her prior to episode. He was the one from their teenage years that loved her. He set up the mother and FL to go to the flash marrige market. He married her ASAP. Now in this clip he is realizing that he is a bit jealous and forcing his ways/rules on to her. He realizes he messed up.She is too naive for someone that old about her 'friendships' and not listening to the whole conversation again and again. I watched this c-drama twice. I love the storyline and acots but the second male and second female lead were too childish with all the yelling, fighting and hitting. Don't have to yell in a crowded place or act out like a spoiled brat.
