So, here most dramas with a time skip where teen and adult version of MC played by two actors and parents played by same actors... Or unrealistically mature children
2. K2 - FL acted like a child. I've heard she was initially written as small girl and it would make sense
3. Eve - FL was played by two different actresses due to time skip 13 years), but no one else changed, it didn't help that FL looked older than her supposed age (heavy makeup). Mains who were supposed to be 15-17 years older than looked like there is 5-10 years between them. SML and FL had 10 years gap but looked like peers
4. Flower in Prison - father and son were played by actor with 8 years gap, and it was visible
Bonus: I didn't watch it myself but I've heard that FL from 30 but 17 (Still 17) was written and acted like 7 yo girl not teen
