Summary from where I left off to the ENDING
So after LBY and SS's catfight lol, SS goes and apologizes to YS. She feels she is embarrassing his family and decides to call off the engagement. The Yuan family gets into some serious trouble (I didn't really catch all the details) but Yuan finds out that LBY has been protecting his family for years while he was in the NW. He went to talk to LBY and he admits that since he found out SS has hooked up with YS, he has been watching the Yuan family extremely closely. LBY wants to protect SS for life and just watch from afar that she lives a peaceful life. At that moment, YS realizes how deep LBY's love is for her and asked LBY that everything he is doing is for SS?! YS had never loved anyone in his life and SS is really precious to him but in the face of LBY, he realizes their love is even deeper. A number of chapters later, YS tells LBY of how SS was after he had his revenge. SS was deathly ill and would be going in and out of consciousness, but she would mutter "don't leave me behind". YS knew all the years SS always had LBY in her heart.
YS tells SS everything. The Queen also passes. SS decides to go away I think to clear her mind or to do something, but LJT unknowingly has been tracking her and plans an attack SS. Thankfully after following LBY for a number of years, not only has she learned a lot of battle tactics, she also had been studyinh how to make fire bombs so she was able to fend off the attack. LJT suffered huge losses but managed to escape. LBY shows up and they reconcile at this point.
They are trying to track down LJT and finds her and her entire group slaughtered in a really gruesome manner. Then they find out YS and the Yuan clan have gone missing. They find him eventually deep in some kind of dungeon. He was captured and ends up everything is a trap laid by Wang Yanji. She has been scheming and planning a revenge for her dead husband Lu Ben for years and it's a very complex plan but she had this palace built with underground levels that can collapse and cave in. LBY, SS and gang find this place and gets trapped after finding YS. A lot is revealed here including plans to kill the crown prince. LBY figures a way out and everyone escapes but WYJ dies. Then comes the part when LBY thwarts the attack on the crown prince and SS leads a separate army to protect the nearby village. After this, they reunite and reminisce, kiss and THE END.
I skimmed the epilogue and I don't think YS ends up with anyone but he visits SS often but SS and LBY leave to travel the world. I didn't see any part about them having kids so I am not sure where the full epilogue is but this pretty much concludes Love Like the Galaxy. There are so many side characters, side plots, and schemes that I didn't summarize as I really just wanted to focus on the undying love between the main leads. So far, I think Wu Lei and ZLS are doing an incredible job portraying their characters. I saw in an interview with WL that he wasn't very happy during filming because he was so immersed into his character. Even his friends noticed he was more tense and fierce than his usual self and he realized he was really invested in the LBY character so even his demeanor changed a bit during filming. The interview contrasts A Sun and LBY and the Ashile tribe vs Black troops. WL said LBY is very overbearing and he brings his troops wherever he wants, and does what he wants and is pretty unstoppable. He thinks they are more powerful than the Ashile tribe (I think that is what he said).
Hope you all enjoyed my summaries! Now we can savour the drama slowly as it is released.
