Too Close to Fall in Love

The ultimate "stepbrother" I can't escape from. My father remarried and now I have a younger brother. He is fearless and handsome. To be honest, I'm in trouble because he's really my type. I tried to keep my distance so I wouldn't fall for him even more, but Motoya kept coming on to me and asking if I liked him, so I lost control and we became a bit too intimate... I'm not sure how long I can endure the fierce attacks of my pushy brother-in-law, who keeps trying to seduce me...?! (Source: ShuCream) Note: Includes one extra chapter.
