The problem with Zoey and the MC was that they never really talked seriously. Also, there were unfortunate misunderstandings before Zoey left.
Zoey did talk to the MC about her leaving. Only it wasn't explicitly about San Diego, it was about Miami. Zoey was already toying with the idea and the MC said they could do that. I guess the MC thought they could do that when they graduated high school. But the conversation wasn't serious enough.
After Zoey's grandmother's funeral, Zoey got flowers from the MC. What did the sticker say? "You do" Right after that, she Googles for a surf school.
When they leave at the station, the MC tells Zoey that he believes in you too and that it wasn't just her grandmother who did that.
As you can read, there were some unfortunate circumstances that only came about because Zoey and the MC never talked seriously about their relationship.
In San Diego, new impressions are flooding Zoey. She hears the story of Bret and Emma. The two are not good role models when it comes to relationships and have a negative influence on the immature Zoey. But there is also a Jonah. I think Jonah gave Zoey the motivation to finish her trigonometry degree online. But all this time, Zoey has remained loyal to her MC? Why, really? She thought the MC would move in with her in San Diego after she graduated high school. Lack of communication at the beginning of the interlude. Since the drama was still going on, DPC caused the big misunderstanding of the interlude. Emma's unfounded jealousy and the resulting Rooster Cluck. When Zoey reads this Rooster Cluck, she finds that her family, friends, and the MC can read it. In the subsequent decision of whether or not Zoey should take the phone away from Emma, Zoey tells Emma, and thus the damage is done. Now Zoey makes her biggest mistake. She doesn't call the MC right away to explain the Rooster Cluck. Zoey already knows what damage this Rooster Cluck has done. It's in the answers to the cluck. Who is the wolf? His answer was just one word. So this "wolf" was already mad and angry when the rooster crowed. Yes, it was a mistake on Zoey's part to go to San Diego, but I believe that the breakup of Zoey and the MC came about because of the rooster cackling and that is the real drama. Their relationship breakup was caused by Emma because of jealousy.
Theory:
DPC may be building a mega bomb. At some point it will be revealed that Rooster Cluck was not true. Lies have short legs, as they say.
What if Emma has a relationship with someone close to the MC? It does not matter if it is kinship or friendship. What if that person is an LI? Will the MC overreact again or lock herself in a bathroom?
Will Zoey fight for her MC?
