Disappointed with the end part

What a bad direction at the end ,they didn't show the lead actor face ,it is look like a incomplete ending .Little upset with the last part of the drama , everything is just perfect bit at the end .....

Ending

I thought everything was cute and all but the very last scene was a little bit confusing and disappointing. I don't know why they didn't show Sooyeon's face when Yeoreum hugged him when reuniting after one year? Yeoreum was crying full of emotion but they didn't show his face. They could've at least shown his face tearing up as well... Other than that, I thought the ending felt very short and rushed compared to the other episodes. It would've been better if they had one more episode or make this episode a long one explaining what happened the whole year he was gone.
