friendship drama???

when finished watching above drama...which is a popular drama acting by korea's actor/actress,different character brought to me different message.I think almost people been watched..then what message can be learn through it? For me,it seem to show that love and friendship..among friends will help each other no matter in what situation..when comes to love,friend will stand beside you and think who be the person suitable together in a couple?And at the end...friend stil friend...they won't get angry when someone is together with your lover because you notice that she's not belongs to you and happiness is the most important when you want to see happy ending...an add on message to share was those attractive scene in this drama...
