Looking back on the first thirty years of her life, Xie Yanli can't help feeling that she has regrets.
If only she'd gotten that difficult math problem right back then, might she have had a chance to get into her dream university?
If only she'd been more proactive in the group interview, might she have landed a job at the company she wanted?
If only she'd been a little more forward with her crush, might she have found a way into his life?
If only... she could really go back to that time.
This is not a wish-fulfillment story!!!
