"오늘도...봄날이다..이뻐이지?" Those were the young Taehyung's last words to Irene. They were only 10 years old when Irene was rushed to the hospital because of a serious heart disease. Only to wish for her quick recovery, Taehyung visits her everyday, not even missing a single day without seeing her. But on one particular day, Taehyung was not able to visit her. Until this became constant, it only saddens Irene which triggers her sickness even more.
A month had passed, Irene's condition became worst than before. As she inhaled her last breath, a wish was formed inside of her tiny-illed heart.

"I just want to see him again..."

And the lines went straight.
