When the System Is Too Boring, Run Next to the Protagonist and Knock on CP from the First Perspective

I am a system, I don't know when it became a system. The more advanced system allows me to quickly develop a protagonist and save the entire universe. But is this idiot I picked really okay? Oh no, because of a mistake, I directly became a supporting character beside the male protagonist, which is fine, even though this idiot lost my help, the universe was about to end. But maybe I can do cp at close range. Intention: I don't know if my choice is right, but he is still waiting for you, the world needs you!
