Pink & Habanero, Vol. 2

Mugi's been doing the best to keep the secret of Kurose Kei's part time job, so she should be the only girl at school who knows the aloof pretty boy spends his evenings serving parfaits and tea while dressed as a knight! But one day, Mugi receives an anonymous, threatening letter ordering her to stay away from Kei. And once he finds out, boy, does it ever tick him off! Looks like Kei's the only one allowed to push Mugi around!

Volume 2 of the Pink & Habanero manga series by Alethea Nibley.
