Forgotten Title : Looking for a Drama

It is about a lady who is in love with a guy but ends up having to take care of his delinquent younger brother

I think the younger brother was living outside the country, some loan sharks were involved, possibly foreign loan sharkers

The younger brother might also be an high school student 

It should be a drama from the early to mids 2000s

Thanks a bunch, didnt think I would find it

and also mydramalist forums finally has notifications lol
