イチゴ哀歌～雑で生イキな妹と割り切れない兄～

When Kouta's father remarries, the new stepsister who moves in looks like a dream until the parents leave the room and Aika drops the act. In private she is blunt, foul-mouthed and endlessly rude to him, while playing the flawless daughter whenever adults are watching. The two fight constantly, but Aika slowly warms to Kouta's patient, caring streak, and her irritation turns into something closer to a crush.
