"Kumau tak seorang 'kan merayu"
I can't explain it well, but I understand. Since this sentence is poetic, only literature people can explain the meaning of Kan in this sentence. But overall, it means that "I want no one to seduce me."
Sedu, Sedan, Sedih, Perih
For these words, all meaning of sadness and broken hearted feeling. You know the feeling when your finger get cut off by a knife? that's Perih feeling.
That's all I can explain :)
