A mini dress that I prepared for this special day. I glance the mirror to see if I look pretty. I want to surprise him with the cake I baked last night. Can't you feel what's in my heart?
Your anticipated birthday. Happy, happy, happy birthday. You might not know, oh, you're so special. Even if the many days pass by, I'm right to you like today. I want to congratulate you, oh boy!
Come into this dark room. Shh, blow out candles. Come closely and sweetly. Do you want to match our lips? In surprise, your glances seem awkward. Don't know what to do. We matched our lips again and stopped.
Your anticipated birthday. Happy, happy, happy birthday. You might not know, oh, you're so special. Even if the many days pass by, I'm right next to you like I want to congratulate you, oh boy!
I couldn't tell you the words I wanted to save for this day. You're the one I want, you're the one I need. Yeah~ I'll tell you today, \"I love you, I love you.\" I'll be here for you! I feel love for real!
Your anticipated birthday. Happy, happy, happy birthday. You might not know, oh, you're so special. Even if the many days pass by, I'm right next to you like today. I want to you, oh boy!
