Recently, Lee Sang-in from 'Raising a Child - My Precious Child' succeeded in completing a marathon with his eldest son, who has an autism spectrum disorder.

On the afternoon of the 28th, Channel A's 'Raising a Child - My Precious Child' revealed the final story of 'actor Lee Sang-in and a mother on the brink due to raising three sons.'

The youngest hit the eldest hard on the head with his fist after the eldest refused to return his picture book. The mother, seeing this, held onto the youngest and disciplined him. The stubborn youngest showed no signs of remorse. Oh Eun-young pointed out that the youngest's biggest issue is 'doing what he wants.'

Lee Sang-in and his wife began disciplining the youngest, who was doodling on the dining table. The youngest resisted, clenching his fists at the command not to do it. The child bit down hard, trying to hold out against the discipline. When words failed, Lee Sang-in threatened, saying, 'Dad will go. I will go far away.'

Next, Lee Sang-in was seen challenging a marathon with his eldest, who suffers from autism spectrum disorder. Upon seeing this, Shin A-ra exclaimed, 'It's so impressive.' Lee Sang-in ran while carrying his struggling son on his back.

Lee Sang-in asked, 'How is it to run with Dad?' and the eldest replied, 'It's good,' smiling. After getting down from his father's back, the eldest diligently ran with him. The eldest said, 'I will be a cool older brother to my younger siblings,' and Oh Eun-young remarked, 'It makes me tear up,' red-eyed.

Oh Eun-young said, 'I've cried so much. I understand how many hardships you've endured. I know how worried parents are for their children and how many tears they shed,' while showing signs of sobbing.
