6.  30 but 17.

Technically, that one is uncle-nephew. The ML doesn't have a brother. Not sure if the topic poster wants to count it or not, but they are close like brothers so.....

7. Ruk Nee...Jhe Jud Hai - FL and ML's brother are best friends actually.

30 but 17

Good one but Yoo chan is ML's nephew not brother, but i'll accept it cause they have a good sibiling relationship.
