My Childhood Friend Is Actually the Male Lead of a Regret Novel

Many years ago, Chen Tang read a regret-themed novel called "After I Died, They All Went Mad with Regret."

That night, a meteor fell. He touched it and transmigrated into the novel, becoming Chen Tang, the protagonist's childhood friend.

He wanted to save Liu Yan, the male lead, from the death that awaited him in the future.

From childhood, he played the villain and sabotaged every romance Liu Yan might have had. But when Liu Yan and Xia You suddenly started dating in their first year of college, he realized... perhaps the male lead's fate couldn't be changed after all.

Then, during a meteor shower before the Dragon Boat Festival, he thought: If I touch a meteor one more time, maybe I can leave this world?

But... he couldn't leave. Instead, Chen Tang became Chen Tang, a girl.

What does that even mean?

You're telling me I've become the male lead's childhood sweetheart?

The world's timeline has changed?

So how am I supposed to save him now?

(Urban campus setting, no supernatural powers or anything like that, gender-bender romance. P.S. I'm trying a genre I haven't written before. My previous stories always went beyond transcendence later on... This one is purely about emotional push and pull.)
