There is an entire series that goes along with the second story. It starts with High School ☆ Lullaby. What the second story portrays is how the main protagonist in HSL becomes the kind of person he is. He is really sweet and innocent on the outside, liked by everyone, but inside he is a demon. His encounter with his neighbor taught him how to be this way. So, as a stand alone, it is kinda harsh, but as a supplement in the series, you get a deeper understanding of the character.
Thank you so much for the clarification, Mameiha! I went and hunted the other translated stories and it definitely makes a huge difference in providing a full fascinating picture!
I'm glad! Even if you don't like the character - honestly, he is not exactly the most likable character out there - readers should at least understand how he got that way. LOL His story won't make you like him, but it does make him hard to hate.
Yeah...I found the last story repugnant.
