Wolf Falls in Love with Moon

Ryuna Kamikawa is the beautiful and perfect-acting student council president. When she gets angry at her lazy vice-president, Yugi Tsukiyama, he likes to tease her by calling "wolf-senpai." The two are like the light and dark sides of the moon, total opposites who don't get along. Until one day, when Tsukiyama discovers the hidden side of "Wolf Senpai" through his secret part-time job...? This is the start of a love story between two people with hidden identities!
