From Forbidden Garden:
Chaos and mayhem is afflicting Yoshida Akari's school. There is a ruthless bloomer thief on the loose-and no one is safe!
But on a more serious note, Yoshida Akari's best friend, Hayakawa Maiko has been missing for 3 days now, and it seems as though no one is making any head in the investigation. So, Akari decides to take things in her own hands and questions the last person who was with her best friend, Student Council President Morishita Natsu. He quickly gives her the brush off stating that he is too busy with the bloomer incident.
Who is this mystery thief and just what exactly has happened to Maiko?

From Beyond the Sky:
Tohko and Wataru were childhood friends. Wataru was rather wimpy so Tohko always had to protect him from bullies. Then he and his family moved away to Germany, and they lost touch with each other.
Years later, Wataru returns to Japan alone for his first year of high school, when Tohko is in her second year of high school.
However he's completely different from what he was like before, having grown extremely tall for his age and much more pushy and aggressive. Tohko is bossed around by him all the time, and even ends up having to make lunch for him everyday, but she doesn't know how to deal with the "new" Wataru. Although he seemed like an angel to her when they were kids, now she sees him as a demon.

The Antique Store Onohara Hall's owner is 16-year-old high-school girl, Yoshino Hara. One day, a guy who proclaimed himself as 'Conan', Ninomiya (age unknown) and two suspicious men dressed in black came to find a ring which had been stolen by previous workers!

Taken from Michex: MITSUKI is on top of the world when IMAI, her former tutor and sister's friend, agrees to begin dating her. Even with the seven year age gap, she's determined to make it work, even though she hardly ever gets to see him. But her happiness slowly gives way to doubts when a year passes without ever breaking down the barrier she feels between them. Does Imai-san even like her at all? Or is the person he's really in love with her older sister and he's just going out with her because he didn't have the heart to turn her down? Maybe he doesn't take her seriously because she's still in high school? When she's with him, he always seems more of the serious type---but what is this about his playboy past?!
