prologue

It was a coincidence that Park Jisoo became housemates with Kim Taehyung, whom she rejected back in high school. Just like two complete strangers living under the same roof, both of them minded their own business.
Their peaceful way of life all came crashing down after an incident one night. Taehyung told Jisoo that she was sleepwalking.
She was distressed, but had no idea how to react.
"Last night was probably the first time you've seen me sleepwalk, right?"
Taehyung drawled, "There was another time."
Jisoo was silent for two seconds, before she hesitantly asked,
"Then... Did I do anything?"
"You came over and hugged me."
"?"
Taehyung raised an eyebrow and casually added,

"And you kissed me too."
