@4sarah1212 u would be surprised about how easy it is sometimes, i cried on command when i was 17 to convince my friend's girldfriend to help me study for a chemistry test, im surprised it worked coz she really didn't like me coz he didn't have too much time for her due to hanging out with me, she even hugged me until i stopped crying and later we became good friends.
Weirdly enough i only did that coz he(my friend) wanted to go buy a present for her but couldn't think of an excuse, so yeah, acting can be really easy sometimes, hell i didnt even watch korean dramas back then
