She was the professor-sharp, composed, and distant. She was the student-curious, hopeful, and in her final year. Their love bloomed in the quiet corners of the classroom, hidden in fleeting glances, unsent messages, and the unspoken warmth between lines of lecture notes. Despite the odds, they fell-deeply, silently. On the student's birthday, they broke all boundaries and vowed forever, marrying in secret on the day she was born... and reborn as someone else's wife. But fate doesn't favor forbidden love. As the seasons turned, so did hearts, secrets, and sacrifices. Their happiest day became the timestamp of a goodbye no one was prepared for. In the end, the professor taught her one final thing: how to live with a love that couldn't stay. "Some lessons aren't written on the board. Some are carved in the heart."
