i still don't quite understand what kind of relationship does suha and his family have with the director and the grandma ???

Lol, that's all BS...

Yep. Even if Granny likes Suha, she's not related to him in any way. That commenter's mistaking the name of Suha's late father with the name of Director Park's older brother/cousin who's still alive even if we haven't seen him yet (but his name keeps coming up in the characters' conversation, so his introduction is only a matter of time). That brother/cousin and Suha's dad are two completely differerent and unrelated people.
