I think, the situation will not arise if Kavya will forgive or not, as it looks like Adi will not make any mistake, he may be framed here badly again.
Of course, he would also be at fault to even doubt Kavya and trust Anubha and reach to that stage.
(based on all the bts and outfits of Kavya and Adi it looks like he will be framed here)
Firstly, Kavya goes to Babua for work with Shubh, and Adi will be informed by Giriraj (may be Seema, Shubh and Anubha too involved separately if not together) that she is elsewhere with Shubh.
Next, Shubh will send a pic of him and Kavya lookalike, which Adi will assume to be true.
Adi would want to question/discuss with Kavya and he will be stopped by Anubha purposely, somehow he will go to Kavya.
Kavya will not listen to Adi, as she would be called by Secretary, so she will ask him to wait and leave.
Next, Kavya finds the last call on Shubh's number was from Anubha and Adi not reached home as she informed by Malini.
(so Adi must have gone to Anubha assuming Kavya doesn't love him anymore/loves Shubh, based on the pic he seen)
Next (yesterday's precap) Adi questions Kavya about if she loves Shubh, to which Kavya mentions how could he suspect her, she even trusted him during the SH case when all the evidences were against him. Adi begs her not to leave thinking she doesn't love anymore, to which Kavya looked surprised, which means, Kavya must have asked him the reason and Adi must have told her about the pic from Shubh.
So, there must be some reconciliation between the two and Kavya must have assured him that it must be fake..etc.
(from start till here, Adi's outfit was same)
Next morning, Adi starts to avoid Anubha (he is already in guilt) and decides to not take Anubha for some secret mission, to which Kavya (being unaware about what happened between them) asks him go with Anubha and Adi arranges pooja at home.
Kavya looked completely ok with Adi here (which means previous night they have sorted their differences, but it was not about Adi and Anubha, it must be about the pic from Shubh).
It looks like, Shubh and Anubha must have planned all this to push Adi to a point of emotional breakdown and frame him, so that Kavya leaves him finally.
It looks like, Adi will live in this guilt that he made a mistake (of course reaching to that point itself was his mistake), whereas he may have been framed again (of course what actually happens between Adi and Anubha is still unknown).
Adi will try to hide this from Kavya and live in guilt and keep helping her, until the truth is revealed and Kavya will connect the dots about the pic sent by Shubh and call from Anubha to Shubh on the same day...etc. and there may be more for her to suspect Adi being framed.
It looks like, it will be a repeat of SH case again and Kavya will prove Adi innocent again.
There is a bit of hope that the makers will not take Adi's character to that level where he will cheat Kavya and make this beautiful relationship look completely wrong.
