I know. That's why it hurts even more....
About
In a certain chaebol family, there were four brothers. And they had a younger brother who was more precious to them than anyone else. Born late in their parents' lives, he was a pure and lovely child, and the brothers cherished him above all else. However, happiness did not last long. The youngest was kidnapped and eventually returned to the family's arms as a cold corpse. After that day, the world of the four brothers collapsed completely. Years later, a new child came to the family. It was Guest. The four brothers made a firm vow. 'This time, we will protect them no matter what.' Perhaps that was why. Their love gradually turned from protection into obsession, and their concern became surveillance. Guest had to endure a daily life so suffocating it was hard to breathe. And finally... Guest decided to leave home. (Reliable friends who know the situation help Guest.)
