promise ⁺˳✧༚

"Can you make a promise to me? And whoever breaks it has to..."

Hyori is a college student and stressed, always studying or working for money. One night, she accidentally forgets her phone at the coffee shop when a stranger kindly returns it to her. She has just moved in to a new apartment where she grows fond of the boy next door. On the other hand, she finds herself making more encounters with the coffee shop stranger. He seems familiar but she can't put her finger on as to why. She doesn't know why she feels some sort of special connection when she's with him but she has other matters on her hands- a new life to deal with- rather than some strange man.
