If he say he is a friend, is it normal to drive someone home who's actually drunk? Plus the 2nd ML is there, and he likes FL, would he let him? No! He might rather have the female friend help her instead. Ml is using the safest option, although it backfired real quick hahaha
The ML is too dumb to say that she was her cousin, I mean theres like a LOT of options to tell who he was to her and he choose cousin?!
