Mizuki Shioko

When her grandmother passes away, high school student Kajitsu Toda suddenly finds two hot stepbrothers and an adorable little stepsister dropped in her lap! Kajitsu and her step-siblings have only one thing in common: they were all abandoned by their parents. Against the odds, they've pulled together to form a family without grown-ups. They don't want charity, they don't want pity… they just want their dignity! Things are particularly tough for Kajitsu and her step-brother Natsu. As kids, they were as close as any true siblings. Now, reunited for the first time in seven years, they've grown as far apart as two people can be. Can they ever become friends again? And can two high school students living together, even as "siblings" ever escape scandal?

Determined, talented and good at pretty much anything, Machiru is the most popular girl in school. She's always striving to better herself, and won't give up on anything -- especially when it comes to love! She and Suruga have been friends since childhood, but when his attention turns to the shy, quiet Hanakago, she can't stand the competition, and suggests that all three of them date! Things are going just fine at first, with Machiru and Hanakago alternating lunch periods and between-class breaks, but the rest of their friends are not coping quite as well. Can three people really be in love? (from mangaupdates)
