A simple question, "are you okay?", gets a simple answer in this short poem: yes, of course. But the speaker lets us see what the answer hides. The real thoughts running through their mind don't match the words they say out loud, and the poem is built around that gap.
The image of "sweet honey" filling the lies is the most striking part. Honey is pleasant and smooth, and that's how the speaker makes the false reassurance sound: easy, soothing, convincing. Yet calling these words "lies" shows the speaker knows exactly what they're doing. The final line, "I am fine it is okay," is set far off to the right and has no punctuation, so it reads like something said automatically, a phrase repeated so often it's become a habit. The title, "Fallen angel," suggests someone who seems fine on the surface but feels something has broken underneath. The mood is quiet, lonely, and tired, the feeling of hiding pain behind politeness.
