Pakistan is not happy because now they are leaking their wounds they lost golden opportunity to win this series and good points in first test now second is already end in draw and most chances third is also going to end in draw because too much rain expected so this series is going to end on just first test result which is clearly not good for them but England is also not happy as now they are feeling they can do some more good after winning first test.
Pakistan might be happy as rain prevented them to be 0-2 which means they are still having decent chances to square the series rather than being already lost the series. The 3rd test is going to be played at Southampton which might be flat surface then there would be a decent chances for Pakistan players to score more and to put England to chase to make them feel the pressure to defeat England.
