Music

Can someone help with a link to the OST or where i can get the OST? That is one of the saving powers for this drama. I have almost finished watching this and so far, it is good. I am loving the second couple but it doesn’t look like they may end up together. Hopefully, I am wrong and hopefully the main couple have a HEA. Anyways, back to the music, I could not find any of the songs by Shazam and I usually find most OST's Shazam. I think the songs here were specifically coined for this drama. Can anyone help, please? Thank you.
