Asahi-kun to no Kurashi wa Dekiai ga Sugiru

Ayano, a fledgling BL manga artist, had been dating her boyfriend Kazuki for a year and they just moved in together three weeks ago. But Kazuki got fed up with Ayano's lack of life skills and dumped her. After a night of drinking, Ayano was almost attacked by a stranger on her way home, but she was rescued by her ex-boyfriend Asahi. And Asahi ended up living with her in the same room where she used to live with Kazuki. Asahi seems to be up to something, but Ayano pretends not to notice...?
