Complicated Complicated...

Got a complicated problem from a friend..apparently..it concerns about relationships...

C used to like A (perhaps a crush), but upon knowing another person, D..
C begins to like D...
C and D get along very well as close friends..
D never express any feelings for C..but there were some misleadings that there is a possibility that D might have some feelings for C..
But perhaps D likes another person, E...
And recently, another person, B might have some feelings for C...

A could have liked C..and if both expressed their feelings earlier...they might be together..But all this is fate...If it isn't yours..it will not belong to you..

D is rumoured to like A before...but things didn't work out between them..

C and D seems more further distanced apart...due to E (common friend of C and D). Despite E's intrusion, C still like D.

And finally, B who has been treating C well..

These five people...such a complicated relationship...that I can't even help my friend a single bit.. I only told my friend to go by the heart..

Anyone else can help or give some comments?
