Sorry, Big Sis, They All Want to Eat My Heart

My name is Lin Che. I have a terminal illness. Ever since my parents passed away, Lin Zhi, my big sister who raised me like a mother, has been the only reason I have left to stay in this world.

For my sister's sake, I have to stay alive!

But the System tells me that I can only extend my lifespan by dating pretty girls.

So, despite having been single since birth, I started reading How to Become a Scumbag.

"Don't rush me. I have my own sense of timing. I'll take Nianhe to the amusement park today, and go to the hot springs with Yiyi tomorrow..."

"Hehe, little brother, I seem to remember you didn't have much of an appetite when you were young~"

Then a cleaver came within 0.01 centimeters of my throat, and I panicked on the spot.

"System, System, give me the most honest and straightforward answer you can. I won't die if I become a scumbag, right?"
