Manga Like Invitation of the Mystic Messenger

Hana is usually a glass-half-full sort of person, but lately, nothing seems to be going her way. After yet another fruitless day of job hunting, she finds herself pouring out all her frustrations to a stranger in the street. The kind stranger disappears before they get a chance to exchange names or numbers, however, leaving behind a phone with nothing but a single messenger app. “Can you read this message…?” As soon as Hana logs on, username “Unknown” tells her they know the person she is looking for. Although a little suspicious, she is intrigued. Who was the stranger that lent her a shoulder to cry on? Who is this “Unknown” she is chatting with? To find the answers to her questions, she must first accept a mysterious invitation. (Source: Tappytoon)
