Clips play in YouTube's own player, and watching is always free. • Read Hangul From Zero — A guided beginner course takes you from your very first letter to reading real K-drama words in about an hour. Native audio for every letter, syllable-block practice, no romanization crutch. Finish to earn a badge and a ready-made review deck. • Write Hangul — Watch each letter write itself, then trace it with your finger, stroke by stroke. Stroke order and direction are checked; a shaky hand isn't. Hints instead of fail screens. Practice all 40 letters and earn the Hangul Writer badge. • 4 Starter Packs — Top 75 K-Drama Phrases, 69 Travel Korean, 52 Daily Conversation, 50 K-Drama Food & Dining.
