How to Protect the Frail, Beautiful Bottom from the Obsessive Top

I was transmigrated as side character #1, who gets brutally mu*dered in a hardcore, dark, R-19 BL novel. I tried to avoid my fate, but when I came to my senses, I had already become childhood friends with the obsessive top who will kill me and the frail, beautiful bottom I’m supposed to covet. Since it’s come to this, to prevent the terrible ending, I’ll raise the bottom to be healthy and nip the top’s obsession in the bud from the very beginning! I interfered whenever the two of them were together and fed the bottom nothing but delicious food, giving him chubby cheeks. Nevertheless, the top’s obsession with the bottom only grew more and more severe. Since I couldn’t keep them apart, I decided to help their romance instead. At the academy, I blocked every single man who showed interest in the bottom, of course, and I went around with my eyes ablaze, making sure no one could even approach him. But it seems my plan has failed. I just feel bad for our poor, frail (though robust in others’ eyes) bottom. There’s no other choice. Since the plan failed, I might as well run away. “Where do you think you’re going, Freesia?” “Ca-Calix?” Damn. The top found me. Since it’s come to this, I was about to beg him to at least not make my death a painful one, but… “…Hah. You thought I was obsessed with Camel all this time?” “You know, our Freesia. You’ve always been so dense.” At some point, the atmosphere around the top changed as he looked at me. To think the target of that dreadful obsession was me… Wasn’t this supposed to be a BL novel?!
