After his
talk with Rukia, Tamaki tried really hard to mask his concern for Kyouya, but the more he watched for it, the more he realized Kyouya's poor health. His lack of energy [1], the fact that he would often leave the room [2] (probably to faint or come close to fainting). Sometimes, Kyouya didn't meet Tamaki until late in the day [3], and Tamaki knew that was only because he needed to gather his strength to go out with Tamaki, and sometimes, when Kyouya was especially ill, he would leave Tamaki for the day to hid his illness [4].
Finally, Tamaki knew what he had to do. He had to confront Kyouya, and tell him it was okay if he was in poor health. It was the song that Kyouya dedicated to Tamaki to show that he cared for him as a friend that got Tamaki to finally decide that he, too, should be a
real friend to Kyouya. Tamaki could take care of Kyouya when he was ill, Kyouya didn't need to deal with it himself.
It was late the next morning [5] when Tamaki decided to go see Kyouya. Carrying a cup of coffee which he had made
all by himself [6] just for Kyouya [7], he headed toward Kyouya's home, and barged in.
"Kyouya!" he called, heading to his room to wake up his friend. "Wake up!"
Tamaki just regretted not noticing it earlier.
[1] Everyone had a lack of energy compared to Tamaki.
[2] Bathroom breaks, mostly.
[3] Kyouya liked to sleep in.
[4] They'd be together for hours and Kyouya would finally decide to go home.
[5] It was already roughly 7:00 A.M. by normal time standars. It was inconcievable to think there might still be people asleep.
[6] It was incredibly watery. Tamaki hadn't realized that you needed to change the filter after each pot of coffee you made. Give him a break, it was amazing he managed to figure out the damn machine (it had only taken the park four times to fix it before he got it).
[7] He had already drunk a pot. He was wired.
