When you get lost in your own music.
When you've physically pushed yourself so hard that you collapse on the ground panting, and you can't help but smile.
When you get an exam back and it reads "100%".
Taeyeon.
When you're walking through a field in a summer afternoon, with no shoes.
When you're with a group of friends trying to solve a very challenging question, and after what could be hours of arguing, erasing and out right screams of frustration, you finally get the answer. Then you look back at all your work and the table top covered with eraser shavings and with your arms outstretched above your head, you laugh.
When the girl you're crushing on says your name.
When you've studied so long and so late, you fall asleep on your books.
When your program is successful after hours of trying to find your error.
When you sing even though you know you can't.
When you fall asleep to the sound of the rain against your window.
When you get a letter in the mail saying you've been accepted into the university you've been dreaming of going to since you were a kid.
When you're around people you love.
When those people you love love you back.
When you write an exam, and you know exactly what you're doing.
When you're not taking humanity courses.
When you're upset and all you want to do is scream, so you find a place to yourself and you let it all out.
When you unintentionally post a wall of text.
