A bittersweet school romance. This drama was more depressing yet fluffy than I expected . To be very honest plot holes are everywhere but a well written heart wrenching love story. They were like star crossed lovers but not meant to be together. Had a good cry watching a drama after so many months. Both of them tried their best to protect each other silently. I got a bit frustrated how the story was going back and forth between real time and college entrance day several times. But everything was worth. Not gonna lie I'm not a very big fan of open endings but i love how the makers left it for viewers to make their own interpretation. But i really wished everything to be clear for my mental peace so I made 2 interpretations but of course i won't spoil here. Read further at your own risk. Contains a little spoiler which is not really a spoiler. So only if she could manage to save him in her 1 year space journey, it would've been the best ending. Happily ever after? No we don't always get a happily ever after in real life. Their fate didn't allow them to be together anyway so hoping for happily ever after was useless. But i still have a ray of hope it was a happily ever after.
