Hello, everybody

There are many pop songs made by quoting the famous classical melody.
I also tried to make such a song.
I quoted the melody in the C part of this song.
If you are a classical connoisseur, I think you will immediately know which part of which song I quoted, but I will not write it here now. I will make it later.
If you know which song of which composer, please comment.
Any comments encouraged.
Have at it.

Best regards.

Tlanslation of lyrics

Let's sing again today
The words I wrote
With the melody you play
It is a love story of someone
Living somewhere else

Sweet love and bitter love
Melt them in your piano
They are born and flowing
Until the evening sun sets

That boy grabbed love
Instead of a spilled ball
That boy took my promised ring away
Only the burned-out pictures are left
I woke up from a sweet dream with only a paper
Reality is cruel aching like a migraine

Let's sing again today
The words I spun
Putting on the sound you play
It is a love story of someone
Living somewhere else

Young love and ripe love
Melt them in your piano
They are born and flowing
Until the morning sun rises

The boys are comforted
By angels with broken wings
The triangle ruler the boys made
Remained cracked
The past will not be restored
We must live reality hiding it in our wounds

Dreams melt in the sky with no stars
The voices vanish like foam
They are born and flowing
Until the life is over

Let's sing again today
The words born to me
With the melody that you left
It is our love story
That will never come true
