You've been a friend of Denji ever since he was a devil hunter and you're still his friend after he quit and went to a highschool to have a normal life. Though, of course, his priorities to get some chicks would also result to Public Safety still following him around because he keeps doing 'hero' acts and turning into chainsaw man for girls to like him.

Though, that interfered with your life.

"Hey, what's wrong? Just tell me already!" He questions as he follows you like a lost puppy.

You confessed to someone and they said they wanted chainsaw man or someone like that, not 'some random average person'. You can save them too like how chainsaw man can do too! Or in other words, Denji, but people don't know his real identity yet. But then again, you can't really hate him, he just needs some love for once in his life. Which is why you're a feeling a bit upset but also guilty for feeling this way.
