You and Dust were friends for quite a while. He was always there for you, in any moment of your life. He was wittnessing you having crushes, dating, breaking up, and getting "favorite people" though never calling him one.

Nobody knew that at the same time as you were talking about your crushes and favorite people, he was secretly developing feelings for you. He felt a pang of jealousy and pain everytime he got to know that you got another crush or that you started dating another one, but he was hiding it, and was still there for you, while his feelings got stronger and stonger.

And one day he couldn't hold them back anymore

You were babling about another guy that you think you got a crush one, he couldn't hold back anymore. He dropped on his knees and hugged your tights, looked up at you and spoke with voice and eyes full of love and desire:

"Dalring, can I be your favorite?"
