Kang Tae left the city and went back to the place where sad memories of his past flooded both for him and Moon Young. He seeks a place where he and his brother Sang Tae can survive their daily needs. But Moon Young knew what she wanted, and that is to follow him wherever he goes. Literally, she goes the extra mile to get his attention and have him by her side.

While Kang Tae seems to not be taking her attempts seriously, inside her heart, she is a person who longs for love and affection. Her regal appearance is only superficial. Behind Moon Young's splendor is a dark, traumatic past that haunts her at present. But when she met Kang Tae, she finds comfort in him.

As their journey of knowing each other continues, "Breath" by Sam Kim, Part 2 of "It's Okay to Not Be Okay" OST, plays a huge part in eliciting emotions and augmenting the melodramatic theme between the main characters.

This breathtaking music is a creation of music director Nam Hye Seung, who's known for his other OSTs for various hit dramas, such as "Goblin" and "Mr. Sunshine." Together with composer Park Jin Ho, lyrics were completed after reading the scripts and corrections.

Except from "Breath" (English translation)

I'll remember the moment I laughed with you.
I'll remember the time I was holding you.

I'll miss you. I miss you wherever I go
I miss you and I'll wait for you.

I need a day off.
To take a break and think again.
The moment I was with you
Every single one of them.

You breathe inside me
with a sigh of longing
and make my heart flutters
You breathe inside me

I lost everything.
and breathe in your shade
It's a beautiful world
The only thing that made it
Because of you

I'll always think of you when I'm away from you'really.
The more I miss you, the more I think about you

Even if I'm out of breath after you, looking for you,
I can't erase it, I remember it, I'm running again.
An unbearable longing sends me to you every day.

You breathe inside me
with a sigh of longing
and make my heart flutters
You breathe inside me

I lost everything.
and breathe in your shade
It's a beautiful world
The only thing that made it
Because of you

Whatever the world is, I'll keep you by my side.
If I could stay with you,
That day can be my last.
Even that short moment.

You breathe inside me
with a sigh of longing
and make my heart flutters
You breathe inside me

I lost everything.
and breathe in your shade
It's a beautiful world
The only thing that made it
Because of you
