Bunkiten Shion grew up with a close friend who became an idol and gained a stepsister after his father remarried. One day, he suffered a fall down the stairs, causing him to lose all memory of recent events—his last recollection being the evening of June 6th when he was on his way to buy a crepe. Upon leaving the hospital, his childhood friend shocked him by revealing they were secretly in a relationship, warning him to keep it hidden from his stepsister. However, things took an even more unexpected turn when he discovered he was also romantically involved with his sister.

Now, Shion finds himself tangled in a web of confusion, torn between two relationships he doesn’t remember starting. His childhood friend insists on secrecy, while his sister acts as if their bond is completely natural. With no memory of how these relationships began, he struggles to piece together the truth while navigating the delicate balance between love and family.

Every interaction feels like a puzzle, with both girls dropping hints about their past together. Was he really dating both of them before the accident? Or is there something deeper at play? As he tries to uncover the reality, Shion must decide whether to trust his forgotten emotions or question the motives of those closest to him. The more he learns, the more complicated things become, leaving him unsure of who he truly belongs with.

The situation grows even messier when his childhood friend and stepsister begin acting suspiciously around each other. Are they hiding something from him? Or is there an unspoken rivalry between them? With his memories still missing, Shion must rely on instinct to guide him through this emotional maze. Will he regain his past, or is he destined to rebuild his life from scratch?

As days pass, fragments of forgotten moments resurface, but they only add to the confusion. A shared glance, a whispered conversation—nothing makes sense. The more he digs, the more he realizes that his relationships might not be what they seem. Was his accident truly just a fall, or is there a darker truth waiting to be uncovered?

Caught between affection and doubt, Shion must confront the possibility that his lost memories hold the key to everything. His childhood friend and stepsister both claim to love him, but their actions suggest hidden agendas. Can he trust either of them? Or is he merely a pawn in a game he doesn’t understand?

The answers may lie in the events of that fateful June night—the last thing he remembers before everything changed. But until his memory returns, Shion is left with only one certainty: nothing in his life is as simple as it appears.
