Hyesung was at Taeyang's place and tried to make a slight move on him while he was sleeping. But Taeyang moved a little and Hyesung got scared and ran away.
On his way out, he bumped into Taeyang's older brother. They went to a convenience store and the brother asked about Taeyang's school life. The brother started talking about how Taeyang cried in the hospital when he was in high school, feeling like a burden. So the brother told Taeyang to go to University of Korea to take his mind off things. Hyesung told the brother that Taeyang's doing okay in school, just eating, sleeping and studying.
(This part was really emotional and lovely, honestly, I'm sorry if I'm being a bit mediocre in summarising this)
Then Hyesung went home and his brother Byeol was mad at him for being gone all day. Hyesung just hugged him and joked around.
Later, Hyesung got a message from Taeyang asking if he got home safe. Hyesung smiled and blushed, feeling happy. He told himself to be patient, but he couldn't stop thinking about Taeyang. So he started singing the Korean national anthem to distract himself (≧∀≦)
