Welcome to the Dreamland Cafe! The First Story

Haruka is a no-nonsense girl who lives only for her studies. One night she falls asleep while studying, and finds herself from a mysterious coffee shop between dimensions. The cafe serves not only mythical creatures but also people who've gotten lost between planes of existence, and it's ran by a super-handsome but mysterious barista. Now Haruka has to learn the meaning of love in order to return home.
