Cold Heart - Daerin

Haerin, a reserved and seemingly cold senior, harbors a secret crush on Danielle, a bright and cheerful junior. Despite her growing feelings, Haerin struggles to express her emotions and instead distances herself, afraid of vulnerability. Her best friend, Minji, notices the tension but remains supportive, especially since she has her own secret-she's been quietly dating Hanni, Danielle's best friend.

As Haerin and Danielle cross paths more frequently through school activities and their intertwined friend group, Haerin's facade of coldness begins to crack. Danielle, unaware of Haerin's true feelings, is drawn to her despite the senior's aloof behavior. The two share moments of unspoken connection, but Haerin's hesitation continues to build walls between them.
