The Terminally Ill Side Character is Healthy

After dying at the age of 30, I was reborn as the male protagonist’s childhood friend in a romance fantasy novel. But as my luck would have it, I’m a minor character fated to die at 18 from illness.

In the original story, the male lead develops trauma from his childhood friend’s death, causing him to initially reject the sickly female lead before eventually falling in love with her and living happily ever after. And I just had to be that ‘childhood friend.’

Dying young is bad enough, but I have no desire to leave someone traumatized on top of that. I have no choice. In this situation, I can only use my transmigrator’s knowledge to the fullest.

Plan A: Avoid becoming friends with the male lead.

“Young master, you will definitely regret becoming friends with me.”

“I’ll never regret it.”

“…You just spoke informally to me.”

“Friends are supposed to speak comfortably with each other.”

Because the timid kitten evolved into a brave, stubborn kitten, this plan failed spectacularly.

Plan B: Run away before dying so the male lead won’t be shocked.

I managed to escape, but…

“I’m screwed. Why am I not dying…?”

Something seems to have gone terribly wrong.
