Crying and Begging [LEE HI X BTS]

World always looks brighter when we were younger, but everything changes when we become adult. The laugh and happiness that I shared with them was the best time that I won't forget. I want to stay like that forever.
I guess, it's just a foolish wish.
If only I try to care more. I can see their crying and begging clearly.
Because, that's my only regret.
Jimin... Jungkook... it's not too late, right?
