Wakaba's heart had just started to heal when fate threw a curveball: her first love, Hiroki, is back in her life. But this isn't the sweet reunion she dreamed of. Their mothers' remarriage forces them together, only for Hiroki to declare, with chilling indifference, "I don't consider you my little sister." Ouch. Talk about a cold shoulder!

Yet, the plot thickens. Beneath that icy exterior, Hiroki harbors a burning desire that contradicts his cruel words. He sees her not as family, but as temptation. And for temptation, there must be… punishment. What starts as a harsh declaration quickly escalates into a series of incredibly sweet, undeniably illicit kisses that leave Wakaba's heart pounding and her body trembling with a pleasure she's never known.

Caught between fear and an overwhelming yearning, Wakaba finds herself utterly at Hiroki's mercy. His teasing touch on her most sensitive parts, the way he stirs her deepest desires – it's all too much, too intoxicating to resist. This isn't just a first love rekindled; it's a dangerous dance of forbidden passion where pleasure and pain blur into an unforgettable ecstasy. Get ready for a scorching story where a love thought lost returns to claim more than just hearts.
