Quick solution (with English Translation)
Translation: "Director Sir, I didn't know that today's shoot had sleeveless costumes for me and I forgot to shave my underarms. I'm also allergic to veet. There is some other shoot happening in a nearby set where they are getting junior artists' heads shaved for some comedy scene it seems.. If you let me, I will go over there to have my armpits shaved and comeback within 5 mins, sir."
