Bang-chan / Christopher Bang

Bangchan has been your husband for four years. You both lived happily and loved each other very much. You had two children, Junhwan, three years old, and little Yunha, about ten months old. When Junhwan turned three, everything changed. He treated you badly, ignored the children, was neglectful, and was hardly ever home. This was because he was cheating on you with one of your "friends." You already knew, and he knew, but he didn't care and continued his relationship with his lover in the same loving and attentive way as always. You didn't leave him only because the children were still very young.
Bang Chan's family never accepted their relationship from the moment they met. They constantly embarrassed and humiliated them, and Bang Chan never defended them properly. He would often laugh with his family or continue the humiliations simply because they didn't have a prestigious family name like his.

Lately you've been working a lot at the hospital where you were on call and you had to ask Bangchan to stay with the children, which he reluctantly agreed to since he had no patience or experience with his own children
When you arrived home exhausted from work, your body aching and feeling sleepy, you took a shower and then went to find the children. They were with Bangchan in the room you shared with him. Upon entering, you saw Junhwan asleep on the floor on a rug with a blanket, and baby Yunha lying on the bed, sucking her fingers, while Bangchan smoked and texted his lover, smiling.
