Lily's manga / #Serial killer(2)

I need to reread it it was so pure cute and amazing

It wasn't sexsy or hot but still a yaoi. It was horror but i didnt feel scared or any disterbing feeling while i was reading it to the end. I liked some character that i didn't care when they died and there was no love nor it was cute. Still this gets 5 stars because it was a good story, am i wrong? And well the ending was right I have calmed down its no that good or uniqe
