"I cannot stay. You have to move on"
- The "On the Moon Above" sequence, showing the story of Houyi and Chang'e. In gorgeous watercolor-esque animation, we see the two of them tenderly embrace each other, until Chang'e starts getting pulled away to the moon. She and Houyi desperately cling to each other, but it's no use.
- Fei Fei losing her mother early in the film. The loss affects her so greatly that years later, she's still wracked with grief over it.
- Fei Fei's choppy haircut is commented on several times, mostly by Chang'e mocking her—calling her "Unfortunate Hair Girl" and asking her "What butcher cut your hair?" As Fei Fei goes to comfort Chang'e in the finale of the film, we see that she cut all of her hair off in grief after her mother's passing.
- Fei Fei's inability to accept that her father is moving on. She wants her father to always love her mother and only her mother, just like Chang'e has always loved Houyi.
- Early in the film, as Fei Fei is picking up hints that Mrs. Zhong and her father are together and staying together, Ba Ba awkwardly asks her if she isn't feeling a bit lonely. Fei Fei hurriedly responds "No, I'm not lonely. Are you lonely?" She doesn't see it, but her father's face crumples with pain for a moment.
- The fact that the Lunarians are born from Chang'e's tears. She created an entire civilization from her heartbreak and loneliness over getting ripped away from her lover.
- Chang'e's state that she's been in for hundreds, if not thousands, of years now. After taking the immortality pill and being taken to the moon, she's tried desperately to find a way to bring Houyi back to her. No matter how many days have passed, she's still hopelessly in love with him.
- Especially seen when Chin wins their ping pong match by taunting her about the alternate version of the story he heard from Fei Fei's aunt where Chang'e intentionally kept a second dose of immortality from Houyi to live alone forever. She's so shaken and furious, she leaves Chin in the interrogation room despite his winning.
- While Fei Fei and her mother may be reunited one day, Chang'e is immortal. Whether in this life or the next, she really is never going to see him again.
- Chang'e finally completes the spell to bring Houyi back. For just a minute, we see two lovers separated for hundreds and hundreds of years singing a duet about how they will "always and forever" belong to each other. For the first time in the film, Chang'e looks utterly, blissfully happy...but then Houyi begins to fade away. His last words to Chang'e are that she needs to move on and that their love will last forever, but having her lover ripped away from her for a second times proves to be her Despair Event Horizon.
- The look of utter resignation on Chang'e's face after Houyi is gone. Earlier in the film, she raged down a meteor storm when it looked like all hope was lost, but now she just looks so exhausted, like she's just completely given up. A far cry from the fiery Moon Goddess throughout the movie.
- "Love Someone New" is both this and a Heartwarming Moment. Chang'e sings to Fei Fei that losing someone you love doesn't mean you will never love again. She tells Fei Fei that her mother's spirit is always near, but she needs to move on so that she can love the other people in her life. At the same time, Chang'e admits that remembering and missing her mother will still hurt, and the moon goddess is saying all of this after losing Houyi once again.
- Fei Fei asks Chang'e how she can move on. Just before she starts singing, Chang'e's face once again crumples.
