Abhi does not have to do anything. Arohi will do all the play. Akshu more than being jealous she will be sad bcoz to instigate jealousy in Akshara only a third person can do (like Ruby).
Arohi might go and fall on Abhi purposely… have a coffee date, do a couple dance with him (tose naina laage re piya Saawariya) and tell him “best ko best hi milna chahiye”
