Inferno significa 'infierno' y se usa para describir un fuego grande e incontrolable, o una situación caótica y destructiva. Es una palabra dramática y poco común en las letras de canciones.
En esta canción, Drake la usa metafóricamente para expresar la intensidad de sus emociones. Canta: "An inferno starts forming inside" (Un infierno empieza a formarse dentro), lo que sugiere una pasión o un deseo abrumador que lo consume por completo.
This is a song about falling for someone so completely that it stops feeling like a choice. The opening lines say it plainly: her eyes kill him slowly, an inferno starts forming inside every time he knows she is there, and he has never felt so alive. Attraction here is not gentle. It burns, and he lets it.
The middle of the song is where the feeling turns into a plan. He talks about giving her all his time, walking the line, taking her home to meet his family, changing her name. That last line is a marriage proposal hidden inside a love song, and it arrives without any build up, which is the point. He is not weighing this. He already decided.
He also knows what she does for him. She brings out the best part of him effortlessly, and he asks her never to dim the light. He wants to be held as close as she can manage until they are ghosts, and he calls that a promise rather than a wish.
Then the song lets the mask slip. The ending repeats one plea over and over: please, do not leave me, you know I need you. All the confidence from the verses drains out and what is left is the fear underneath it. That repetition is the real subject of the song. The tie that binds is not only devotion, it is also the terror of being the one who cares more.
