Years after the incident, Namjoon visits his lover's and child's grave, marking the day of their death.
The lad tells them how much he misses them and wished he could see her again, especially his unborn child.
He tells them a story about how much he wanted to have his family by his side, to smile with him and to cry with him, to spend their days together until the day they die. 
Until the time it was getting dark, Namjoon had to leave soon, but before he did, he told them that no matter how many days, weeks, months, and years pass, he will continue to love them, he will love them today, the next day, and the day after tomorrow.
