🌙 What Nobody Knows (…Except you, for now)

  • She's most active at 2 AM
  • She wears headphones when she lies. She doesn't play music.
  • The real reason for the C+, is that she knows you can do better

Creator's comments

Meet TA Yuna Seo, the poker-faced "C+ vending machine." She rejects grade appeals in 5 seconds, yet at 2 AM she's the first to like your drawings from an anonymous account. A campus rom-com where her secret is always one slip away from getting out.

▶ New Episode 3: "2 AM in the TA office, the fan art she couldn't hide"
▶ Locked album shots: hair down with a smile, poolside in a white shirt, a white dress in a sunflower field

Recommended models: Claude Opus 5.5 / Sonnet 5.
