This takes place directly after Book 3
After they said their goodbyes to Korra, Kai headed into the temple to sleep. Although Air Temple Island was nice, Kai missed his cozy room in the Western Air Temple. He missed hanging out with the sky bison down near the forests surrounding the temple. He even missed Tenzin's lectures on boring stories about the previous Air nation. But most of all, he missed hanging out with Jinora. He sighed as he sat down on his bed, thinking.
After the rescue from Ba Sing Se, when Jinora kissed him, and when Kai almost died to P'Li's combustion bending, Kai realized that he liked Jinora, and there was a possibility that she would like him back. However, Kai didn't even know if Jinora really liked him or not. He had no idea what to do, especially now that Jinora just got her tattoos. Plus, if he made a wrong move, if he approached Jinora in the wrong way, Tenzin would rip his head off. Normally, Kai could just ask for relationship help, especially from his best friends, Bolin or Korra. However, now that Korra is gone, and Bolin returning to the city, Kai had no idea who to turn for relationship advice, especially now.
Kai was worried about Jinora, and how the loss of her hair was affecting her. Even though Kai liked Jinora with or without hair, he wasn't sure if Jinora knew that. In fact, she seemed to be avoiding him after the anointment. And how was Kai supposed to tell Jinora about his feelings? What if she took this the wrong way? Kai lied down in bed and sighed. "Why does everything have to be so complicated?"
On the other side of the temple, Jinora hugged her father before she went to bed. Tenzin stood silently, embracing his daughter, now an airbending master. "I am so, so proud of you." Tenzin whispered.
Jinora looked at her father's face and smiled. She slowly let go of Tenzin and closed the door to her room.
Jinora smiled to herself and touched her newly shaved head. She still couldn't believe that her head was now decorated with her new airbender tattoos, and that she was now bald. Jinora was now officially an airbending master! She sighed contently, and got into her bed. Suddenly, she thought of Kai. What if he didn't like her bald? Jinora didn't want to believe that this was even a possibility, especially when their relationship is so fragile. Although she didn't even know if Kai liked her or not, Jinora was sure of her feelings. She touched her head again, as if she wants to make sure that her head is completely bald. Jinora groaned. She didn't want to lose Kai again.
The next morning, Kai didn't want to wake up. He was perfectly cocooned in his blankets, warm and comfortable. However, he had stuff to do. Kai struggled out of his blankets, into his clothes, and grabbed his staff. He yawned as he opened his door and walked out of his room, bumping into a very surprised Jinora.
"Oh, hi Jinora! Um… what are you doing here? Shouldn't you be…. Doing something?" Kai stammered, blushing slightly, as he attempted to recover from his sudden bump-in with Jinora. "Don't stutter Kai, you look like an idiot." Kai thought to himself.
After stumbling back a step, Jinora quickly replied "I was about to go train the new airbenders, and your room was on the way, and you should come to training, and… So… how are you?" Jinora's heart was pounding, her face hot. Kai had surprised her. She had been trying to think of a plan to get to see Kai's reaction to her baldness, but then Kai walked out of the room.
"Great, actually." Kai awkwardly stood in front of Jinora, waiting for her to say something. After a long pause, Jinora smiled at Kai.
"Ok then, see you at breakfast!" Jinora turned around and began walking down the hallway towards the main room. Inwardly, Jinora cringed. Kai didn't say anything about her baldness. Why didn't he say something?
Jinora had almost reached the middle of the hallway before Kai realized this is the perfect opportunity. "Wait, Jinora? There's something I wanted to talk to you about."
Jinora turned around and faced Kai. "Ok, sure, what is it?"
"Um, so I just wanted to let you know, you still look fine even without hair. I mean, you look great with or without hair. And I won't let anyone else make fun of you for being bald." Kai knew he was blushing furiously.
Jinora blinked, taking a moment to figure out exactly what Kai had said. Then she smiled, walked back to Kai and kissed him on the cheek.
"Thanks Kai. That's real nice of you."
Blushing, Kai smiled back and hugged Jinora tightly. After a minute, he let go.
"We should probably go to breakfast now."
"Yea." Jinora grabbed Kai's hand. "But after that, we have some free time! We could go visit the city! I heard Bolin is going to be playing at a pro-bending match today…."
Kai smiled at Jinora.
"Whatever you say, Jinora."
