Kurai Anoko to Shitai koto

Starting his second year of high school, Ren Tabata was determined to get over his loner past and make some new friends. The first person he approached was the girl next to him, Toruko Sasaki, who seemed gloomy and a little intimidating at first, but he couldn't seem to take his eyes off her. A romantic comedy between two shy but cute people who don't want to be alone anymore!
