I am sticking to my sense that Aryan has known he was attracted to Imlie since he carried her into his house after she fainted in his car. This was even before he knew she was married to Adi. Once he realized he kept away until she was on the streets and needed help. Since then he has not been able to stop himself and has fallen more and more in love. He knows she does not reciprocate his affections and needs time. All his actions are intentionally vague - it can go per revenge from Adi...or love for Imlie and I'll always thought love for her was quickly overpowering the pursuit of revenge. 
He is obsessed with her. He cannot stay away for a couple of hours. Anytime any harm happens to Imlie he is there to protect...he cannot even hear anyone threatening her. He does not care about showing his concern for her before anyone. He clearly says they are not friends and he has shown with his many actions that he is much more than just a boss. With Arpita he said nothing could stop him going to Imlie with or without her approval...he is not looking to hide his love from his sister. Remember the big Sita Maiya gift? 
He will either acknowledge his interest or not tomorrow based on whether he thinks it will bring Imlie to him or take her away from him. He is very measured and careful in his dealing with her. But it is clear that he knows what he feels. No one does all that he has been doing the past few weeks...putting his life on the line...prioritizing her over his family...without realizing their feelings and Aryan is an extremely perceptive and thoughtful man. 
Remember during Adilie rasams, Malini said no one would do so much for a girl like Imlie. Well he is. He will always be there for her and never let her go.
Not accepting his love will not be because he does not realize it himself. i would not at all be surprised if all this comes out tomorrow. It is not hurried because they have been building this for a while and then again Imlie is not in love with him yet...so that conflict is still open. What she does if she realizes he loves her is yet to be seen. She will try to leave R mansion...will he let her?
Adi will not stay in a house bought by Imlie's money..he will likely move to C's?
All the songs they have used for Arylie imply intense passion from his side - and if thats the story its not too soon for Aryan's acceptance. 
Interesting the story is at this point...hope they take it forward well.
