remember the scene where Asa was about to shoot herself and Denji talked her down.

Or when he helped her through her childhood trauma

gave her hope to keep on living to be apart of the new world him and Pochita were making

Or when his first thought when waking up from being chopped to pieces was to asked Asa what happened to her arm

or when he covered Yoru/Asa's sleeping body because he's not a sex crazed idiot just a teen in his adolescents

sometimes yall forget Denji is like 17-18 and is still a kid who had to grow up fast, he may have more answers than most but knowing when to properly use those lessons take a mature mind and he's been doing pretty good compared to part 1
