Both are really short dramas about vampire - human relationships. The human leads are students and the vampire ones are very interested in them.
Both stories are about lesbians who have secretly crush on the female who are around them. Both are short cute stories.
Both focus on dealing with terminal illness, the loss of people important to us and accepting death as a natural part of life.
It is another WHY R U special. It shows some backstage moments. If you liked the first special then probably you'll like this.
It is Ending Again's special episode, so if you like the character and the plot in Ending Again, you can watch it.
