Faithfully, still yours

20 year old, Park Jimin, got cheated on by his rich, CEO intended. But, instead of mopping around, he joined his best friend to a music festival where, against all predictions, the notorious, cold, distant and not-so-much-of-a-talker bassist, Jeon Jeongguk, caught his eyes like a moth to a flame.
They spend months together, until one day Jeongguk was gone without any words, left Jimin ghosted, just like that.

Six years later, Park Jimin, a happy kindergarten teacher in Seoul is extremely surprised when his first love, Jeon Jeongguk, enters the door, leather jacket, combat boots and a 5 year old in tow.
