Affection System: The Way They Look at Me Is a Little Strange!

I couldn't find a 1999 fanfic I liked on Ciweimao, so I decided to write one myself. Please don't flame me if it's not your thing! Synopsis: Su Ze transmigrated, and it had already been six years. He never expected that his System wouldn't unlock until the main story began, or that his special constitution would turn him into a living-daylights version of Tang Sanzang in another world. But in this sick world where magic and technology coexist, even though Su Ze can't fight his way out of a paper bag, his unique constitution and foreknowledge have helped him save many people. And he hasn't been alone on the way: he adopted a little sister and took in a mom. Still, he's been through plenty of regrets and helpless moments... But seeing everyone he's met smile has left Su Ze quite satisfied. A healer must sacrifice flesh and blood, burn their heart and soul, keep hope alive, and save all living beings. Of course, everything should have gone just fine. But ever since the main story began and Su Ze activated the Favorability System, he keeps feeling like countless pairs of eyes are watching him from the shadows. "Wait, sis, why is your favorability score just a bunch of garbled text?" "Why does this one have three question marks for a favorability score?" Hold on! Hold on! Can't we all just talk this out? Don't hit me! Wait! Hey! Hey?! Yamete kudasai!!
