Still remember that summer/No matter how long it has passed, it is still engraved in my heart/Close your eyes and go back to the past/Remember the faces of all your friends/My eyes were red and sad from crying/On the day of the graduation ceremony/Everyone promised to bravely move forward towards/their dreams/Don't forget our agreement/Maybe you will be a little timid/Maybe it is still far away/We will chase the dream together/One day it will come true/fly away Don't forget our agreement...
