Synopsis

A little brother-like secret relationship with his little sister?! A romantic comedy between siblings with a misunderstanding begins! Akira, my stepbrother, was brought into my life as a high school student after my parents remarried. He is a cute boy but shy because of the complicated family environment he grew up in. I had a crush on my brother, so I always spent time playing with Akira for his sake… He loves me… We hit it off, and the distance between us grew rapidly! I asked him, "...Brother, do you like me by any chance?" "Of course I do." The misunderstanding between the two of us deepens. And finally, I realized that Akira was my "sister" and I was confused... "I like the distance between my brother and me as we have always been. I'd rather be with you more than I am now." Akira's approach to me, aiming to make us "lovers" instead of "siblings," has begun! A flirtatious romantic comedy with a little sister who is too cute and carefree to be a brother! https://www.cmoa.jp/title/287517/
