though as much as I enjoyed the story, I still couldn't understand what made Yeon-hee fell so uncomfortable about Ye-na. As far as I can see,they were childhood friends,spend much time together and then Yeon-hee found love with Ye-na.But when she confessed to Ye-na,she said "stop coming" and then completely shut-down on Ye-na.I understand that she had a hard time, but what gives?Nothing bad will happen if they just keep the relationship as close friends like they used to be,and I haven't seen Ye-na do anything bad to Yeon-hee.Someone explain to me the conflict,please?Did I miss something important to the plot?
