So guys, I'll be the one to explain:
- Before his Uncle goes to the joint training, he asked Taeui to help McKean if he asked for help. Then McKean asked Taeui to copy a data and gave a specific time to do it. Taeui did it but while copying the file, he felt that it was familiar and it looked like a chemical formula. Taeui did not complete the task since he felt that it was Jaeui's. He then tried calling his Uncle to ask about it but he was unable to reach him. He had a really bad feeling about the file that's why he went to Mckean and his bad feeling was confirmed after meeting him. The data was a chemical formula that Jaeui created.
Taeui doesn't really care even if they sold nuclear weapons or do something illegal with it. However, he couldn't stand the fact that his uncle illegally stole what his older brother had developed.
While talking to McKean, Ilay went to the room and there, Taeui found out that Ilay knew everything that his Uncle is trying to do and Ilay is helping his Uncle. Tae felt really bad and betrayed
Ilay sent Tae to the detention center. Here, Tae is gradually getting depressed. He's mentally, physically and emotionally exhausted. He felt that everything was piling up and he also had a severe headache. He got out of the detention after a day and he talked to his Uncle over the phone since Uncle is still at the joint training. Tae was really angry and got mad with Ilay as well. He got thrown out of Ilay's room when he burst out of anger. Ilay told him to calm down.
- The morning after, Taeui was still the same. He still has a headache and is still exhausted.
