Description
Im Yoona's phylosophy in life was that nobody gets justice; just bad luck or good luck. This thought changes when a certain someone comes and helps her out like no one else ever had. When Yoona finally realizes she's not alone, that she might be falling for her savior and that her feelings might be reciprocated, things start taking a turn for the worst. Will Yoona be able to hold onto the person who changed her luck?
Foreword
"Yoona-ssi? What happened to you?" Seohyun asked through a gasp as she carefully inspectioned the older girl's features. Yoona looked down again and kept quiet, hiding the fact that she was touched that Seohyun even cared. The younger girl was about to insist when Yoona's hand caught hers and gave it a faint squeeze.
"You're really kind, Seohyun-ssi... Don't ever lose that kindness." Seohyun furrowed her brows and unconsciously held tighter onto Yoona's hand.
"What happened to you?" Seohyun insisted, even more firmly now.
"Don't worry about it..."
"No, Yoona, this ends today." Yoona widened her doe-like eyes; she didn't exactly know what surprised her the most, whether it was the fact that the proper Seohyun had addressed her without honorifics or the fact that the younger girl was offering her the only thing she had been screaming for all her life; help.
