Random question #1

Have you ever felt nostalgic after listening to a random song or, a random scene from a movie or, a random thing while doing your daily chores? I have. So basically there's this song called "Starlight" its an OST from the Kdrama "Twenty-Five Twenty-One", which makes me relive the moments I never think about, sometimes it even makes my eyes teary. 

Listening to this song make me feel good and also sad at the same time, It reminds me of the time when I had a crush for the first time, how I used to wait for him after my classes, how I used to find different ways to make him smile, and how I used to blush whenever someone said his name. Sad? How?

Cause how all those feelings were turned into a memory just in few years, how I waited for us to reunite,

and eventually we did, it was a coincidence but as it is said if it's meant to be, it'll be right?

Then how's this sad? Yeah we reunited but yet the journey was too long and it never ended, we bid goodbyes after seven years of being the best buddies, and you know how it hurts when your best buddy leaves and at the same time you lost the person with whom you fell in love.

Sometimes some songs, some scenes from a movie or a series can make you feel all those feelings that were turned into a memories and the eyes are just teary but somewhere you grew so much that now you're unable to even shed them away, but the feelings are still fresh.

Have you ever felt this way, or am i just being a crazy person?
