Historias de Gurenyuu

Guren and Mikaela are the (overprotective) parents who seem to pick favorites. Shiho is the older brother with his three younger siblings, going in order of oldest to youngest; Yuichiro, Shinoa, Mitsuba, and Yoichi.

After Yuichiro finds Mikaela, Yu couldn't help but keep his mind on his family member everyday, heck, he even won't stop talking about him. Guren starts to feel a little jealous, and he's trying to tell himself that he doesn't like the brat. But what'll happen when Yuichiro finds out that he's been experimented on? And that Guren knew about it? Will their frendship tear apart, or will they continue and they start to feel attracted to one another more than friends?
