Ch 1: Student discovers that his teacher is a vampire and plays with him for a bit. Pretty bland for my taste, and pacing was too fast. Welp, it's a one-shot. 3/10
Ch 2-3: COOL. Pretty weird, I must admit. But I love the unique story Two students meet in the school's hidden science lab, only to learn... 9/10
Ch 4: too fast paced, you don't even feel the characters fall in love with each other. Also, justice for the uke who was raped but got gossiped on by others. Ugh. 2/10
