Mia had realised that she holds no chance, Yadvi is much more emotionally involved with Binu, although she indeed was attracted to her but still strong feelings always overpower fleeting attractions.
Mai stood still waiting for Sam today he would be getting married, these two would be finally getting together, wheather they remain as lifelong lovers or not isn't the question because feelings can change but some feelings like love can last longer that doesn't mean that feeling of love cannot change or turn into hatred, jaelousy.
What's important is that two heart align on their own no force of any kind can make two people fall for eachother except fate, there is no denying that in this life she doesn't have the fate on her side. Maybe just maybe she will also get her happy ending in another universe somewhere far away in another place, galaxy.
