I think niru wil feel hurt that chandu did not reveal to him that sarja is his bro. Chandu knew tht sarja was d one who initialy threatend niru. He unintentionaly never reveald his relationship with sarja to her. I don't think niru cares abt sarja if he likes her or continues to trouble her.( she won't surely like a man running with a gun). But may b she'l hurt tht chandu did nt tell her this. She won't mind chandu being sarja's bro as she can see both r different but he not telling her abt sarja she wil b upset. Today chandu was so cutely trying to propose her but after knwing dis she may refuse chandu.
