"I told people I was happy alone, but it wasn't because I truly was. It was because if I loved again and it didn't work out, I might not make it. 

But you, Kim Yong-sun, you're worth the risk, and I'll work hard to become a better person for you." - Moon Byul-yi 

"You haven't been in my life for long but I can't imagine it without you, 

I'll be the sun to your moon for as long as you'll let me." - Kim Yong-sun

Four years ago, Moon Byul-yi lost the person she loved the most to a car accident. 

After years of feeling guilt and pain, she's finally on the journey to love and healing with the person she least expects - Kim Yong-sun.
