It Ends With Us 2.

As his finger glides over the smooth glass frame, a single teardrop falls from his eye and rolls down his cheek.

His gaze falls upon a photograph of his 4-year-old son cradled in his husband's arms.

He feels as though time has flown by far too quickly, and it seems like just yesterday that his son was born. Memories of his first cry, his first steps, the first time he rode a bike, the first day of school, and the first time he made friends flood back to him.

He remember the way his face lit up when he told him that he was the most beautiful person in the world and that he wanted to marry him when he grew up.

As Taejung celebrates his 15th birthday on Jeju island with the Kim family, Jungkook was alone in the guest room, crying as he recall the moments he shared with his son.

Meanwhile, the Kim family is surrounded by the lively atmosphere of the island, with music so loud that it vibrates the tables.

Young teenagers are dancing and enjoying themselves, including his son, Taejung, who is sitting with his friends on the balcony, sipping on wine and watching the crowd in the pool.
