Title: Invitation of the Mystic Messenger
Hana Kang was not having a very good day. She gets fired from her job, her rent goes up, and as a result, she loses her home. So she goes out into the world with her few possessions, lost and alone. Out there, she runs into a beautiful blond woman who comforts her and asks her to be her friend one day. Naturally, Hana wants to be her friend, too, and after they part, Hana finds that the mysterious woman has left her phone, which gives her the perfect opportunity to seek her out.
However, upon checking the phone for information on the mysterious woman, Hana finds nothing except an app called Mystic Messenger. When she uses the app, she gets a response from someone named Unknown, who points her toward an empty apartment. Little does she know, the apartment and the app are being monitored by members of a group known as RFA – Rika's Fundraising Association – and because Rika has passed, her role in the group is opened, and they all offer it to Hana. So, with a new job, a new apartment, and a gaggle of attractive suitors at the ready, Hana sets off into the unknown.
