As theorized, since HaSeul represents the white dove, a symbol of peace, she must choose between peace and harmony or learning the truth about the LOONAVERSE and gaining knowledge. (As explained above in the Let Me In) HaSeul chooses truth, and decides to kill the white dove, or kill the peace. As a result, she looses YeoJin, her close friend when YeoJin gets lost in the forest. As seen in the description of Singing in the Rain, "HaSeul, who always seems to cause rain wherever she goes" this could suggest her sadness towards losing YeoJin, who was like a daughter to her.
HaSeul has the ability to spread her individual color, green. As we see in Let Me In once HaSeul makes the decision to kill the white bird the snow begins to melt and the world turns green.
In Let Me In, as described by twinfish, the yellow truck represents HyunJin, who has brought HaSeul to Iceland for her to discover herself. HaSeul looks bored or tired in the truck, suggesting she doesn't want to do this, and possibly HyunJin is forcing her to do this. This shows a similar relationship a parent would have with a child, since HyunJin is pushing HaSeul to do something she doesn't want to, and shows HyunJin's control over HaSeul.
As described by Blockberry Creative, "HaSeul is a warm friend who is like a mother to YeoJin", which we can see in the music video for My Melody. We then learn that the reason YeoJin isn't present in Love & Live is due to the fact that she's lost in the forest, and therefore represents the slash in 1/3. This is most likely due to HaSeul choosing truth over peace, and therefore losing the person who brought her peace and happiness, YeoJin.
Her relationship with Chuu is very unexpected, since HaSeul and Chuu are in completely different worlds, with Chuu in yyxy and HaSeul in 1/3. But what we do know is that HaSeul wakes Chuu, who doesn't even see her, and HaSeul gives her a knowing look before walking away. This could suggest HaSeul seeing Chuu's love for Yves as being childish in a way, and that she had experienced the same feelings when she was younger, and understands that its a part of Chuu's child-like personality. (More of their relationship is explained in Heart Attack)

In the month of December,
- The Carol was released
- We know that The Carol happened directly after Let Me In. HeeJin and HyunJin found HaSeul and the three of them went Christmas shopping.
- The Carol 2.0
- This deals less with HaSeul and more with repeating The Carol.
- Heart Attack
- We see the properties of the möbius strip affecting loona directly here. By HaSeul appearing in her The Carol outfit to wake Chuu, she disrupts our normal perception of time. Instead of events occurring normally with Heart Attack happening one year after The Carol, we see the two happening at the same time.
