Hello

or

2.) A Manga about Revenge. Like Kuroshitsuji oder Skip Beat!

or

3.) A Manga with a difficult difficult topic like bullying, self-harm, abuse, stalker, kidnapping, rape or something similar. Like Mars, Konbini-kun or Vitamin.

or

4.) A Manga with a Couple with a Age Gap. Like Castle Mango or Finder.

or

5.) A Manga with two people who are opposing. Popular and Unpopular, self-confident and shy or something similar. Like Calling or Say I Love You.

or

6.) A Manga about a Villian or Anti-Hero. Like Death Note or Code Geass.
