Love Triangle

He was so heartbroken with the way his previous relationship (1st love) ended. This new girl (A) came along, he didnt put much thought into it & decided to just settle. Right after he proposed & in midst of wedding preparation, he met this other girl (B). They were just friends & he became very comfortable with girl B. Love blossoms in between himself & girl B without realizing it. He then realize that girl B is actually The One instead of girl A. Unfortunately he can't call off the wedding because he is from an influential family & words about the wedding are out. Girl B then realize she has feelings for him too but felt terrible about it because she felt guilty about her presence in his life & disrupting someone's marriage. Girl B reluctantly told herself ample times to leave him but her heart is stronger than her mind. They enjoy each others company very much & felt perfect together. He can truly let go and be himself only when he is with girl B. Surprisingly girl B is able to open up his mind to the real & colorful meaning of life again. With girl A, it's a Grey picture & life is meaningless. What should girl A, girl B or the guy do? What a messed up situation! Should girl B stop all contact with the guy and just bare with all the pain in her heart? It will kill both of them....
