About Choro Mesu Days
Takashi starts living with his new stepsister after his father remarries. At first he worries it will feel awkward sharing a home with a girl, even if she’s only his stepsister. When he finally meets her, though, he’s taken aback - her name is Alice, a strikingly beautiful girl from Northern Europe. Part of him is happy to have such a lovely stepsister, yet her unusually large breasts stir confusing emotions he can’t ignore. Still, watching Alice sincerely try to become part of the family, Takashi does his best to push down any impure thoughts and treat her the way a proper older brother should. One day, however, he accidentally sees her naked, and the wall of restraint he has carefully built comes crashing down.
Kotomi comes home one afternoon to find a strange boy sitting in her living room. Her mother explains that her cousin Ren will be staying with them for a week while his parents are away. Kotomi takes an immediate dislike to him - especially his irritating habit of calling her by her first name without any honorifics, as if they were already close.
Things grow more complicated when limited space forces Ren to sleep in Kotomi’s room. That night, after a frightening TV show during dinner, Ren admits he’s too scared to sleep alone. Reluctantly, Kotomi lets him into her bed. At first he simply clings to her, trembling. Then something shifts. His hands begin moving with an unsettling familiarity - slow, deliberate, and increasingly inappropriate.
What follows is a quiet, complicated aftermath.
