Bad Buddy (2021)

Ever since they were young, Pran and Pat's families had a deep and raging rivalry, trying to one-up each other on everything. This also extended to their sons. Comparing their sons' achievements and merits,—whether it be academic or extracurricular—the two families leave no stone unturned to outshine and gloat in front of the other. The rivalry was passed down as a family heirloom and the two boys become rivals in turn. Until... they grow tired and become friends. Really good friends. However, because of their families' rivalry, their friendship has to be kept under wraps. And so began a journey of secret friendship... and then perhaps a secret romance?
