Transmigrated as the Male Idol's White Moonlight

Blurb One: Su Yue died at the age of twenty-five or twenty-six. Her short, simple life was driven by two regrets. First, she majored in finance but never passed the CPA exam she had always dreamed of taking. Second, she had been too shy to confess to her secret crush from middle school, and so she had never been in a relationship by the time she died. Given another chance at life, she was determined to make up for her regrets from her previous life. But now that she was no longer Su Yue... what would become of those old obsessions? She transmigrates into her cousin's body, into a completely different family environment... This time, she will be a top student! She wants a life without regrets! Note: She studies and dates at the same time. I'm terrible at writing blurbs, ugh. Theme:
