This is something interesting and an eye brow raising issue at the engagement ceremony of Selvaraghavan as Dhanush was seen missing the function.

Just wait don't jump into any wrong conclusions as all is well between the brothers. Dhanush is busy with the shoot of Venghai so he missed the engagement function of his brother Selvaraghavan. As director Hari planned to shoot a song and Dhanush's presence is needed on sets at any cost so he couldn't make it to the engagement ceremony. Tamannaah is playing the role of his love interest and will be seen in Indian traditional outfits through out the film. Raj Kiran, Santhanam, Prakash Raj, Ganja Karuppu and others will be seen in the supporting roles.

So, once he is back from Karaikudi Dhanush will be reaching his brother to convey his wishes.
