Looking at you.
I can notice every slight twitch of your fingertips, every slight frown between your brows, every slight curl of the corners of your mouth.
And you don't know who I am.
...
Feeling.
The feeling of being noticed every time I am impatient, the feeling of being cared for every time I feel troubled, the feeling of being caught every time my smile overflows.
I know that there is such a person in the world who cares deeply about me.
