他們倆演技真的很棒❤很自然❤我有看過很多愛情劇，只有這部愛情電視劇是我最喜歡的❤他們對看雙方的眼神和接吻真的很到位❤我給他們100/100❤期待他們下個作品❤

When I watched this scene a second time (and I have watched it several times since then) I came to believe that this was one of the most powerful scene in this series. It seems to me that it is in this scene that he begins to grasp the depth of the pain she has gone through because she feels that she abandoned him and was the first to leave his side when he needed someone to help build him up. She was to be his knight. We, the viewers can see in his body language: the look on his face and the tightening of his arms.

@@gomomma6649 so well said! and i thought this scene was perfectly done as well. emotions and body language were on point. ❤️

One of the best scenes …so moving.. and let’s commend the transition of both through physical aspect ,seeing the difference of what was once a slim college boy and a girly cute girl to young adults ..

l so much love this series
