Takamine is a Liar

Meguru is an innocent high school gal who has zero luck with guys. One day, she was saved from a molester by a mature and tidy office lady, Yukiho. She seemed like the complete opposite of Meguru in both looks and personality, and Meguru pounced on her, asking Yukiho to be her love teacher! Yukiho was confused, but promised to be her friend, but Yukiho's true nature is actually that of a teasing bully...? This is a love story of two unbalanced people. (Source: Ichijinsha, translated)
