I think of you

Han Zixin left the police headquarters after signing the official documents. There was nothing for him to do today and so he decided to give a look at the apartment that he was renting. He stopped in his tracks as he saw a couple of college students holding guitars and playing music to get donations. 

Instead of leaving for home, he found himself walking to them. He put two notes in the donation box and asked if they needed his help. 

"How can you help us?" A boy who was in his late teenage years asked. "You already helped us a lot by putting money in the donation box." 

"Pass me the guitar, " Han Zixin said. "You are collecting donations for flood-affected areas. I just want to help for a noble cause." 

"Can you play it?" The other boy asked. 

"Yep, " Han Zixin took the guitar from the boy and sat on the chair, adjusting the instrument on his thigh. He touched the string once and then twice before he was questioned again.
