I'm looking for some shoujo oneshots whose plots I vaguely remember.

1. The girl transfers to a new school and there's this fierce competition between the classes for a "head' of the school or something. I believe she's the only girl in the school, but somehow she's made the leader of her class, and then during the fight a boy from her class forces her to recall her powerful strength. Apparently they were childhood friends and she unknowingly hurt him before so she repressed her strength. In the end they end up together. That's all I remember of this oneshot.

2. I read this recently. This girl always secretly goes to a secluded area in her school to take care of a cat, as her school doesn't allow pets. Then one day, she finds a boy there who claims to have transformed from the cat. He tells her stuff that only she told the cat so she believed him. She falls in love with the "cat-boy" then later one of her classmates mentioned a famous player from an adjacent school, and she sees the "cat-boy" being close to a girl, who turns out to be his sister. Apparently he has seen her take care of the cat and gradually fell in love with her.

3. I'm actually not sure if this is a oneshot, but I read this several years ago. The girl has a doll that is somewhat magical as it allows a guy come out and take form every once in a special occasion. He gives her some encouraging words and support as she struggles in school, but she eventually gains others' approval as class president and works hard. He also gives her some candy I think, and can use magic to do some miracles for her. That's all I remember of this manga.

4. I just remember that both the heroine and the hero are super smart, popular, good looking, and athletic. The girl is like a "queen" and the boy a "king," except she doesn't want to lose to him and she always does. She challenges him and he usually ignores her. At the end they get together of course.

Please help me find the names of these.

1. Is it NG x Baby?

Found no. 3. It is the oneshot in Otome no Sainou.
