Midorikawa Hikaru - Sono Toki, Kimi Wa Shiru Darou (translation) 歌词

At that time, you should know

That person will hurt your nieve self even though through jealousy or sympathy all your friends have stopped visiting
You should go with your eyes open you should see the rainbow disappearing
*at that time, you will surely know you lost everything at that time, but you should think while looking at the sky, this is for the best
When you return, the looks you get from others will pierce those who were once your close friends will turn their backs on you
If you're lonely, it's okay to cry out when you do, the stars will approve
At that time, you will finally know you are your only friend
At that time, you will keep walking on the road that is yours alone
