2(Kyou Kara Maou)

An Au where Yuui returns to Japan to go to university(he probably studies something that will help him be a better king) were he somehow becomes popular.

No one, outside of a few that went to high school with him, knows much about him but everyone finds him handsome and cool especially as Yuuri is kind to everyone and will help anyone who asks for his help.

So, he gets his own fanclub(he has no idea about it) and many woman(and a few man) have crushes on him and fight to get his attention with him being oblivious to all this.

Until one day, their university informs them there will be an event and they could invite someone from outside their university to participate with them.

And of course our dear Yuuri, who has taken his head out of his ass and finally assumed he was attracted and in love with Wolfram, decides to bring his beautiful fiance with him.

At first everyone assumed Wolfram was Yuuri's friend so they didn't ask anything until someone, who was very curious, asked Yuuri what was Wolfram to him and the answer he got surprised many people and lead to many broken hearts and jealous looks.

Anything else is up to the writer.
