Ore wa Gimai ni Uso wo Tsuku: Chi no Tsunagaranai Imouto wo Ore ga Hikitoru Koto ni Shita

When his troublemaking friend nudges him toward a dating app, part-time worker Rokurou Sanjou never imagines the reckless decision will matter. Yet one night, with alcohol clouding his judgment, he fires off a "Like" to an appealing profile—only to freeze in horror: the woman on the other side is Yuuha, the stepsister he hasn't spoken to since being cast out of the family home two years ago. By all rights, the connection should go nowhere. Instead, against all expectation, the two of them actually match. Swept up in the momentum of the moment, Rokurou makes a fateful choice: rather than reveal his identity, he strikes up a conversation under the guise of a total stranger. What begins as a drunken impulse soon hardens into an ongoing exchange built entirely on a lie. With every message, the deception deepens—and so does the danger that Yuuha will uncover the truth about her mysterious new contact. For Rokurou, whose fragile link to the home he lost now rests on a foundation of secrets, the question is no longer why he started lying, but how long he can keep the truth hidden...!?
