Before entering the house I think abhishake spoke to isha.
I think she told him she is seeing someone. And that as much as she can shel help him in the game. And he said he'd help her if he could.
The abuse for me was his edge into coming in the show. If he was just a random ex it wouldn't be as eye catching
So I think he asked her to say it. Because when they went in the house she said I won't tell anyone about it. And he fought with her for no reason.
He said he liked her. Repeatedly.
And when samarth came into the show he didn't seem surprised.
He told isha to admit to it lol.
Weeks pass. When there's no mention of either of them on wkw they start fighting with each other.
Their fights make little sense because they often end up talking later to each other normally.
Cut to the last episode. The only thing that abjishake had that look real was his love for isha.
So what I noticed even though he ignored them after samarth entered and initially when he had kz.
He started to get jealous seeing them with each other etc.
And cut to last episode he starts crying seeing her leave.
The hug was what gave it away. He didn't want to touch her at all. But cried and kept her stuff.
This made no sense again lol.
