Do parents have to die during the drama? 

If not, 

5.  I'm Not a Robot:  FL raised by her brother after father died before show started. 

6.  Something in the Rain:  ML raised by his sister.  We never hear about the parents. 

They don't have to die during the drama, but I am  looking for the ML and FL doing the raising, not the other way around. I was actually going to do that for another topic when it's my turn again lol.

So these won't count.

7-Kill It: ML raises his protégée

Are they considered siblings?

Numbering is getting kind of messed up. Until Kill It is verified by someone, then I'm not going to count it.

6. Stars Falling from the Sky

6. Stars Falling from the Sky

For Kill It, they weren't related(siblings)

 I AM SHOOKETH:

For Kill It, they weren't related(siblings)

But they did consider themselves siblings or no?

No, he was his adoptive father

7. My Country: The New Age (one of the ML, Seo Hwi raised his sister)

8. Bulgasal - FL raised her sister (both parents died) 

9. The Crowned Clown - ML raised his sister (both parents died)

10.  Jealousy Incarnate:  FL raises her teenage brother.  There's a stepmother around, but she doesn't seem to do any parenting.
