That's just you being a mentally ill schizo who bought into /csm/ shitpost narratives.
There are multiple reasons why Denji is the "center of her life". You might have missed it since you haven't read the manga but there's a Devil sharing a body with her who is obsessed with revenge against Chainsaw Man, who promised to return her body if she goes along with the plan.
She is also driven by guilt from her past actions as well as the fact that her life was saved by Denji, which pushes her to attempt to do the same to him, often in misguided ways.
Asa and Denji also get into conflicts numerous times because their personalities clash.
Of course, the low IQ folks see this as "lack of chemistry" because they expect a perfect romance with totally unconditional and irrational love.
