Thanks for the update, Ratna.
I agree with involving Arvind in their love in unnecessary. It's commendable that they told Arvind about their love instead of giving him false hopes, but now forget about him and come to a conclusion fast.
Arvind braking purposely only raises concern about his real motives .. he still wants to be with her and will plan against them.
All in all, good start and hope moving the wedding day closer will force Karthik & Jyothi to take immediate action.
