I Transmigrated into a Tragic Novel and Started Promoting the Law

[Two male leads + transmigrate into a book + both are each other's first and only + friendship turns into something more + melodrama + fake angst + domineering CEO + youth + a touch of ensemble cast + System + reborn]

A gentle and polite doctor with a head full of thoughts × a controlling, devoted, straightforward, and obsessive CEO

Gu Wen is a lawyer who accidentally reads the angst novel Sorrowful Snow. He rants about how crazy it is, then transmigrates into the book...

He becomes the male lead's personal doctor and friend, as well as the one who brings the male and female leads together. He plays this role to find a way home, but one day, he realizes the plot has changed...

Oh, right! And there's that System of mine that's always sending me off to work everywhere. Why don't you come back and see how badly your male lead has gone off the rails?!

He actually...

Later, he slaps himself again and again. “That's what you get for thinking the mission would be easy, for being such a pushover, for reading this novel!”
