Wait, she’s not my little sister—she’s my fiancée!?
I still remember when Kana used to adore me. Now, Takashi Shiina can’t help but sigh as she barely gives him the time of day.
Then, out of nowhere, his parents drop a bombshell—he’s not their real son after all. And to make things even crazier, Kana isn’t his sister… she’s actually his fiancée!?
This is the ultimate Reiwa-era sister romance manga!
