Pakistan hard work and their luck in this match were so high that no one can think so much and their victory was very close to defeat because the target of their batsmen was not strong but still they succeed with their bowling effort. I do not call Pakistan strong because if you look at the hard work of their batsmen in this match, the target was not that strong and if you look at their bowling, they have succeeded in victory the match very closely but I consider their victory good because it is better than defeat and not bad that they have won the match even after playing poorly. If you look at Nepal bowling, they achieved the target quite well and took 9 wickets but Pakistan's bowler got victory by only 7 and one run in the end with a good effort in which they need a good effort to make themselves stronger than before which is quite important for them.
Pakistan won thanks to bit of luck and bowlers in great form but this was not convincing game. Their batsmen did not perform well to place high total, but bowling department did well enough at other end to win match by margin of three runs. Any win is positive, nevertheless, it is important to note that this win reveals area of improvement in batting lineup. You were also right on great bowling by Nepal which captured nine wickets. In the end, you view this game as learning experience to Pakistan, experience that teaches them of what they can work on to be more complete unit.
