Great but sad

This movie broke my heart! The first half was so heartwarming and cute and then the end was so freaking sad! Honestly if I knew what the outcome was going to be, I would have have skipped on this movie but I am glad that I didnt. Kim Yoo-jung delivered as always but I I wish they explained why the ml died and what happened with the fl bff and the ml bff. I've seen Beyon woo-seok in Record of youth before this and that drama did not give him justice. I can't wait to see future projects that he is working on. He did such a good job with this role!
