Sequel of...

I finally get it! The answer to this post. Remember saying that she had Princess Syndrome? Well, that's only half the answer. The symptoms are very close to... reverse harem/male harem.

First things first: Harem is something only the upper-class men in olden times get to have. Err, here's the article form Wikipedia. In other words, commonly said to my friends - "后宫". That should explain it.

So, about reverse/male harem, it's the opposite. Whereas the common harem had women, this one had men! (Doesn't make sense, because in S- Pistols there're males in the winged race harem.) Two of the most famous animes with such themes are as follows:

I think everybody knows these two. I prefer Ouran over Fruits Basket, cause Tohru is just... how do I say it, too wimpy? These days, Otome games are made into anime for fanservice purposes. Yes, fangirls love them bishies.

Amnesia
Note there's another guy at the back, but you only got 4 lover candidates.

Uta no Prince-ssma (1000% or 2000% Love, dunno)
6++ lover candidates

Hakuouki

I never thought this was an Otome game. I like the outfits~ Around 5+++ lover candidates.

Arcana Famiglia

Unexpected! 7 lover candidates. The Heroine is just so cool!!!!

Starry Sky

12 lover candidates.

Brothers Conflict
13 lover candidates! WOW. Note there's NO FEMALE in this pic.

Now we discuss how Calf is going to achieve her goal of getting her own harem. The similarities in Otome games is all the bishies are head over heels for the heroine. Well, not exactly since the start of the game, but through interactions and decisions made. The best way to start your own harem is to interact more with the opposite sex. Thus the commotion about her boyfriend being jelly. All the bishies in the game are not interested in anyone except for the heroine, so since Calf wanted to create her harem she has to keep the others at bay too, in case they somehow flew off with other women. Why then? She needs superiority. To be on top of the world, to be different from other girls. In other words - 主人公. The only one in her game.
