10 titles in which actors who played a parent and a child have ridiculously small age difference (10 years or less)
They should be biological parents and children in the drama
1. Flower in Prison - Yoon Tae-Won and his father have 9 years difference
2. Nokdu Flower Baek Yi-Kang and his mom, it was required by the plot that ML and his mom are closed in age as she got pregnant by her master at very young age, but actors were born the same year, so it was too little
Bonus: Hospital Playlist - Peter/Dong-Il and Rosa, they had almost 12 years difference as a son and a mom. There was even a ametajoke in S2 about their age difference
