From Perfect Illusions:

Reo-chan, a first-year girl, gets dumped by her boyfriend because she's not skilled in the home economic traits he believes women should have. Her ex tells her that she must apply to a "housework" club before he will reconsider going out with her. Therefore Reo-chan has little choice but to join.

Here's the catch: the only members are four gorgeous bishies. The other first year in the club, Irinaka, competes with her a lot. As the story progresses Reo and Irinaka get forced into a lot of interesting situations together and in the meantime become closer and closer.

Being beautiful is never easy, especially if you're an eighteen year old boy like Yoon Da In who is constantly mistaken for a girl because of his delicate good looks. Da In is, in fact, anything but delicate. He is the ringleader of a group of tough kids in an all boy's school, and he's quick to beat the living daylights out of anyone who even hints that he resembles a girl. If that wasn't hard enough for a regular teenage guy to cope with, his life is about to take a shocking turn for the worse. When Da In stumbles upon strange happenings in the forest, he gets sucked into a world of vampire intrigue and sinister romance that he never knew existed. And he learns that there are worse things than being turned into a vampire: being turned into a girl?!

Momoko is a girl who was born into a witch family in which most of its female members possess magics. Yet they can only reveal their magical capability to "the one" i.e. their soul mate/spouse. The more magic she uses in front of strangers, the more parts of her body would become cat-ish (such as cat ears and whiskers), and if any stranger learns her true identity she would turn into a cat completely--like her mother!

Having joined the magic club in her school, Momoko has used her ability too often that her cat ears pop out every once in a while so she must find "the one" as soon as possible, but her candidates have already become suspicious...

It's the start of high school, and Kako decides to "produce" her bookworm of a childhood friend, Kousei, so that he can become a good-looking and popular school idol. She models him after Lawrence, a character in a manga she likes, but as Kousei's transformation becomes a huge success and he extends his new character beyond what she asks for, what will Kako do? Will she find herself left behind in the wake of his newly found popularity?
