Sikky-RK-Deepali

First love triangle of this show. A base. It was, it is and it will be a trouble maker of RK and MB's love story.We don't know very much about it. Only that Deepali betrayed RK and married Sikky. But how much loved RK his first love ? Is possesivness and opsession a part of his charakter ( not only in this case with MB) ? Was or is he opssesed wit Deepali too ? How can he live in the same house with her and Sikky ? Has he still feelings for her ? Is it normal to marry a girlfriend from half - brother ? Is that for Radhaji ok ? What thinks RK about Sikky ? Can Sikky stay an idiot his whole life ? What will happen and will open his eyes ?
