thanks to hama57 further elaborating the story of ep 15.
Yes the scenes for Joonsang & Yujin reuniting in ep 14 - 15 are touching and full of feelings -- it was a dating that delayed for 10 years and finally they came back for each other !
The polaris they promised to each other and then Joonsang gave a gift -- polaris necklace as an everlasting promise -- in the snowball is better than in the pink mitten ? but here in ep 15, the director is trying to combine the two important "gifts" together -- both were promised by Joonsang and Yujin was longing for 10 years...this is most important and promising !!
Yes, packing the polaris necklace in the snowball was really romantic in the original version.
The two arrangements - one is romantic and the other is more meaningful ...haha, both are acceptable ! thanks
