Hi! Quite complicated isn't it well no. Firstly I'm not sure if a similar one already exists, do let me know if it does(I'll delete this one). 

So, here's how to play

You are supposed to name a drama having the other Lead of the drama above as lead(IDK how to explain TBH :'))

2nd person : W- two worlds apart (Lee jong suk)

3rd person: Happiness (Han hyo joo)

4th person:  Strong women Do Bong soon (Park Hyung sik)
