Movie Story : Mera Bhai Season 1 follows two brothers whose love-hate bond is tested by their completely opposite personalities. Bittu, the elder brother, is in his final year of college and focused on landing a job placement. Sittu, the younger brother, is in 10th grade and seems far too relaxed about facing his board exams in the same year. Their clashes and close moments make for a comedy-drama about the most relatable quirks of brotherhood.
