Since DMG is heavily reliant upon Bollywood for ideas, me thinks Ridzy will sing that Kate nahi kathte song from Mr India, in front of everyone to say 'I love you' to Armaan - that's probably why Sangeet is being introduced...? She was seeking ideas from Shash anyway..
Not sure about the surprise party though - it may just be for Rahul, which Ridz had arranged when she didn't know about Armaan's dushmani with Rahul.. Having said that can't understand why she has to be nice to Rahul when she could so obviously see that he had squealed on Armaan about the half-day thing - she saw it with her own eyes, if I were Armaan I wouldn't speak to her for days till she came to her senses - stupid girl!
Armaan is at his best when he enacts romantic scenes - it's so much more natural. When he does this funny guy act, he goes a bit over the top - i know, i know many find it cute, but I find him the best when he is serious with Ridz or teasing Ridz 😛
