Answer 2

shining friends-冯曦妤

a little faith
brightens a rainy day
life is difficult
you can't go away

don't hide yourselves in the corner
you have my place to stay

sorrow is gonna say goodbye
opens up
you'll see the happy sunshine

keep going on with your dream
chasing tomorrow's sunrise
the spirit can never die

sun will shine, my friend
won't let you cry, my dear
seeing you shed a tear
make my world disappear
you'll never be alone in darkness

see my smile, my friend
we are with you,
holding hands

you have got to believe,
you are my destiny
we're meant to be your friends
that's what a friendship be
