| 「IF YOU DON'T KNOW」 | |
| Talking about love | |
| What is and what would never be | |
| When you're full of love | |
| You're full of kindness | |
| Talking about love | |
| What is and what would never be | |
| When you don't feel love | |
| You're only spoiling | |
| If you don't want to be mistreated | |
| Learn it right, boy | |
| Let me see your smile | |
| And so I can feel you closer | |
| When you're full of smile | |
| You're full of happiness | |
| Let me see your smile | |
| And so I can feel you closer | |
| Never faint youe smile | |
| You're only lying | |
| If you don't want to be mistreated | |
| Learn it right, boy | |
| Wake up, open your eyes, | |
| and think what you have done so far | |
| If you don't know how to use | |
| your energy and power, learn it good | |
| Better learn it | |
| Wake up, open your mind, | |
| and think what you have said this time | |
| If you don't remember, | |
| wake up, so you would know | |
| what's right and what is wrong | |
| What is right and wrong | |
