Is Spring Days coming back?

An orphaned girl, Seo Jung Eun, slowly comes out of her reclusive and silent shell with the help of an old childhood friend, Go Eun Ho, a physician. They fall in love and promise to marry when an unexpected accident causes Eun Ho to first fall into a coma and then amnesia. During this time, Go Eun Sub, the half-brother, befriends Jung Eun and against his better judgment falls in love with his brother's "fiancée." What ensues is a heart-wrenching love triangle that is complicated by the three characters' love for one another that transcends any love they may feel for their heart's desire.
