Knock knock knock, excuse me
Please come outside
Your parents will be disappointed
Hurry and open the door
What are you doing in your room, lalala
What are you doing, sitting down lalala
Stop sitting there and open the door

Hello, open the door
Hello, open the door
Open the door, hello

* Are you just letting a day go like this?
Open the door
Are you just gonna sit all day?
Hello
Hurry and take a late step forward
Open the door
Open the door to your tightly shut heart

** The morning has come, the sun is rising
But you’re not opening your heart’s door and not coming outside
Why, oh why (oh why, oh why, oh why) exactly why, why hey
(Oh why, oh why, oh why, oh why)

Hello, open the door
Hello, open the door
Open the door

Every day every night
You’re staying home all day
Staring at the clock and just being lazy
Stop watching TV, your eyes will fall out at that rate
You don’t even know how to play, you don’t know anything
Hey (open the door)

(Hello) The sunlight is warming but what are you doing in your room?
On this long day, you hold onto your game in distress
Stop, at this rate, your future is so obvious
Don’t hang your life on it, at that rate, you’ll really get sick
Snap out of it and look at the mirror
Your dark circles fall down, down, down
Throw your hands up high

Hello

* Repeat

** Repeat

Hello – open it, open the door, the door
Open the door
Hey dude, open that locked door
Hello, open the door
Open the door

The closed (Door door door door door door)
Open the door (Door door door door door door)
The door of your heart (Door door door door door door)
Open the door (Door door door door door door)
Open the door

Starting now, one by one, open the door
Starting now, one by one, show us
Laugh more than anyone else
The door was once closed but right now
Open the door
