This drama had an intriguing story line, lovable characters, a whole lot of heart, and plenty of laughs all while managing to wrap up in a way that was satisfying to me (despite breaking all my pre-conceived rules about time travel...which I suppose doesn’t matter much since there are no rules to fiction). Yun Si Yun plays yet another adorable, perfect man-child that the world just doesn’t deserve. All the supporting cast was wonderful as well. While I wouldn’t necessarily call this a re-watcher it’s 100% worth a run and I guarantee you’ll laugh and smile your way through.
