❤I've been used to reserving myself. Only by doing this won't I get hurt when I'm leaving.❤
❤No matter what have happened and whether you are ready or not, every next moment is gonna be a brand new start.❤
❤Whatever you do, remember that you do it for yourself, then you will not complain.❤
❤If you get tired one day, you will see my smile as long as you turn around.❤
