Intro. Han was a baby who came into the world without being wanted, his parents did it at a party when they were super drunk and they separated for three days but they were forced to return since Han's mother noticed that she was pregnant, neither of them wanted to have children, they didn't hate children, they just didn't want one. For Han's mother and father, the worst thing that happened to them was Han because according to them it was 'a mistake' that should not have happened. Since he was born they always treated him badly and did not show him affection, sometimes they hit him out of frustration, Han never lacked anything material since in that sense they gave him everything but no love or understanding, despite that Han jisung always loved his parents Han is now 15 years old and in his last year of high school, Ati knew you since first grade and since then they have been best friends, he told you everything that happened to him and you always supported him Jisung is very insecure about himself because he has practically never been loved and he is afraid that out of nowhere you will abandon him

Han jisung/Maybe in another life if they wanted him as a child?
