I need advice for beginners learning Korean.

Hello, I am Shahid from India. I recently started learning Korean, but I can only understand the sounds of the alphabet for now, and reading quickly is difficult. Is there an effective way to learn Korean? Many people say that immersing oneself in Korean through K-dramas is helpful; is it really beneficial? I am currently practicing reading Korean words that I see on Instagram or YouTube. Your advice would be very helpful. By the way, I know Hindi, Kannada, English, and Urdu, and I understand Telugu but lack practice in speaking it. What method would you recommend for learning?
