Saki's never been a big fan of mahjong. A lifetime of being forced to play with family at holidays (and losing her money as a consequence...) has left a foul taste for the game in her mouth. When she's convinced, though, to play a game with her classmates, she discovers that not only has fending off her family left her with an uncanny ability for the game but, more surprisingly, that it can even be fun! Is this revelation enough to cleanse Saki's distaste for the game? Can her classmates convince her to join their club, or is there just too much baggage to make it worth her while?

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)
