Here’s my thoughts from the point of a novel reader as well…
When I read the novel, this was one of my biggest theories that I think it’s most likely true:
1. Chirpie is described as a round white bird. The bird that circled the tree and has Yoohyun’s original body was also described as a round, white bird.
2. Chirpie is said to have “two” personalities sometimes, a very intelligent one and another that is constantly hungry for gems.
3. Gems are said to replenish monsters’ energy. In order for the White Bird to meet Yoojin, I would have to expend a LOT of energy, making its obsession with eating them make sense.
4. The fact that Yoojin can’t read ANY of its stats means that it is probably stronger than his skill (it was L rank right?) meaning Chirpie has to have power strong enough to break the system, or be too strong for it to register.
5. When Yoojin was in danger, Chirpie briefly awakened/unlocked an ability. This ability had something to do with the stars and was extremely strong. This shows that if Chirpie had all abilities unlocked, they would be star based and extremely powerful.
6. The white bird that took Yoohyun’s OG body went missing around the same time that Chirpie appeared. I doubt this is just a “coincidence.”
7. The white bird specifically takes ONLY Yoohyun’s body, most likely to save it from being destroyed along with the OG time line world. The white bird then preserves the body in a way that won’t allow it to decompose or be destroyed, obviously saving it for someone.
8. The constellations while talking Yoojin mention that the white bird left in search of someone AFTER taking the body. This probably means that the white bird was probably trying to take both Yoojin and Yoohyun’s body.
9. The white bird’s ability are all in some way related to time and space. Time is a very important theme in this story. Most likely, due to the extreme use of her time power to see Yoojin, the white bird was reduced to Chirpie.
Personally, this story is actually really complicated with time and interference playing a major role in it. Multiple times during the story and especially later on, this becomes really clear. In one of the more recent arc of the novel, the plot of overlapping time becomes very twisted and people appear that shouldn’t. The universe that Yoojin occupies is very shaking and this is due to much of the constellations’ interference. Chirpie is just one of these cool details. Also, sorry for rough grammar, I’m not very good with English.
I totally agree with you guys. The moment I saw chippy's appearance and the white bird was mentioned like they have white body, same species and abilities. It totally clicked my mind
Ay yo dem white bros deffo have smth to do with our lil' Chirpie!
I think Chirpie is the mystical white bros that leads to the tree of origin. Just my guess, but it would make sense if it was. And it was the 'key'.
