Conquest of Anime Male Leads

I was browsing Bilibili when I transmigrated? And got bound to a System!

The System said, "Please protect the male leads in each world, help them find their female leads, and make the male leads fall in love with them."

"Got it!"

Just as the protagonist was going to great lengths to find the female lead, they suddenly realized:

"Wait, System, something's not right! I think I'm the female lead!"
