The Shiunji Family Children

Honestly, I was really happy……when I heard none of us were related at all…! One fateful night, the Shiunji siblings’ lives were changed forever when their father revealed they were never really siblings! Now, eldest son Arata finds himself surrounded by cute girls unrelated to him by blood, all of whom have suddenly started acting awfully suggestive. His youngest sister, Kotono, even confessed her love to him! But they’re still family, and nothing more…right? Arata’s struggle to keep his sisters happy and to suppress his teenage urges has only just begun!

With youngest sister Kotone’s declaration that she wants to marry her big brother Arata, the love story surrounding the siblings of the Shiunji family becomes even more complicated! No matter who ends up together, it’ll be a forbidden romance!

“To me, you’re my cherished twin brother…and I guess you’re also the one I love.” Now that they know they aren’t related by blood, the Shiunji siblings are beginning to look at one another in a different light. While eldest son Arata tries to resist his younger sisters’ advances, his twin, Ouka, is overwhelmed by her own budding feelings. She runs off on a weekend retreat for some respite—or so she claims—but days later, she still hasn’t returned! Will Arata find her before she goes missing for good?

Arata is at a loss after Ouka kisses him out of the blue. What will he do with all three of his younger sisters now showing signs of romantic attraction toward him? In the meantime, all the Shiunji children take a trip to the mountain resort town of Karuizawa!

Kotono, Minami, and Ouka confessed to one another their feelings for Arata and formally declared themselves love rivals for his affections…and Arata overheard the whole thing! Now he’s stuck keeping his mouth shut as all three of them become increasingly aggressive in their appeals—and they’ve done their research to learn how to sweep a man off his feet! The first true test of Arata’s willpower comes when Kotono, the sister who started it all, asks him out on a “grown-up date”…
