Negative Emotions Recycle Bin

I am Mo Xin, and I opened an emotional recycling bin. The world pays me the library, and I forget it for them. I thought I was just a heartless eating machine until Lin Xia showed up. She begged me to take away her happiness, but that stuff was like poison to me. What's even more frightening is that I found that I felt the thing I longed for and feared most from her - warmth. Now, she's my employee, my guinea pig, the lingering warmth in my stomach. And I'm worried that before I can understand her, I will have "indigestion" and die of this terminal disease called "heartbeat"
