I think this MUNNA is Addu only and pretending to be Munna!
Possible story can be... Munna & Addu were friends, and Munna ne addu ka Brainwash kiya hoga, saying that his family is not finding him cuz they are happy without him etc. Etc. As they were kidnapped kids nobody recognize them easily from their names... Hence, after the real Munna got lost or died or whatever 😕 Addu took his Identity so that nobody can find him, & also, due to all those brainwashing he must hv developed hatred for his family and to take revenge he gradually became DADDA's trusty...! Now, he is making his own story to reveal the reason of his stay, without revealing his identity to Ragini
I might be wrong but m damn sure this guy is Addu only, and after misunderstanding Meghan together his hatred has reached to its peak 😔 GOD SAVE MEGHAN PLZZZ...
