Novel & Cerita Cast Of The World Of My 17

I've been telling friends to watch 'Thirty But Seventeen' whenever the mood calls for a warm, slightly bittersweet rom-com, and the core reason is the leads. The drama stars Shin Hye-sun and Yang Se-jong. Shin Hye-sun plays the woman at the center of the story — she was a bright teenager who, due to a long coma, wakes up years later as a thirty-year-old with the emotional world of a seventeen-year-old. The show explores how she relearns everyday things, reconnects with life, and handles the gap between her mental age and physical age.

Yang Se-jong is the other half of the pairing: he plays the man who becomes her anchor. He's kind, patient, and quietly carries emotional baggage of his own, so their chemistry is built on awkward, heartwarming, slow revelations rather than instant sparks. The series leans into their relationship as a gentle study of healing and growth, with supporting characters rounding out their community and adding both comic relief and obstacles. If you like character-driven plots where two people help each other grow, the performances by Shin Hye-sun and Yang Se-jong are the main draw here.
