And epsecially when BR cried, gosh, no one can be sympathize with her feeling than SW. They all cried for their father and they always had each other's warm hug at that time. No one can cherish their father more than BR and SW. That's why this scene is so beautiful. It leads to the scene in 2016, that SW calls BR and talks about papa Sung birthday, and BR is the one know best about her dad's shoes/trainers size. This couple make sense as always.
