Explanation from a friend.

After Myung-Dae excused himself from the breakfast table, I too finished my meal and took the father to his Chambers to get him some rest. I made a routine for him to follow, a routine always helps to get better. How our roles had been reversed, I had no idea. After leaving him in his bed to get some rest, I made my way to the garden. 

I will take father here today, he would love this garden.

My father and I had always been lovers of flowers. According to him, I got it from my mother, and he was also because of her. I guess he really loves her because his eyes still sparkle when we used to talk about her. But the sadness within them, it is something only I can see.

Sitting one of the chairs, I got rid of my shoes and stared into space, relishing the feeling of soft grass under my feet. I smiled, nature always surprises me. Leaning back onto the chair, I saw someone approaching me, after getting a closer look, I was sure that it was Byung-Woo.
