When the 9 year-old Oh Sehun meets a 7 year-old girl encountering the same fate as him, will his cold-heart waver? Will he learn how to love in a limited time? Will his unwanted fate change? 

2 fates collided.

2 lifes on the line.

Time was ticking.

Will there be a happy ending? 

Leukemia. The disease that was slowly taking their lives.

"Was there any hope to live?"

"Hope is always there for you, you just have to believe in it!"

"Thank you for staying with me all this time and thank you for teaching me how to love."
