Liar Liar

Minato, a plain and clean-freak college student girl, lives and goes to the same school with her younger brother-in-law of the same age Toru who is a beautiful playboy and popular with girls. Minato often gets into trouble because of Torus bad behaviors, and forces him to write a written pledge stating no access within a radius of 10 meters in order to break off any connections with him.
