Lee Hyejin was hopeless when it came to love but that didn't stop her from chasing romance when she could. She'd developed crushes on seven boys over the years, none of which remained in her life for very long. In order to let go of her feelings for them, she'd write them a confession letter each before stashing them away in a box. The letters were her own little secret. But now all her crushes are back. And they have her letters with them. [ Inspired by to all the boys I've loved before ]
