Time travel story always have been a fascinating theme for me, and this drama provide that. To be honest, episode 1 is kind of boring and confusing, but I'm glad I didn't stop because of that. A little bit cheesy, but it's funny and quite entertaining. I cried for Goro at the end of episode 3 and early episode 4. Poor him (T^T) Separation part is quite touching, but Kuroshima Yuina's cry is not too natural.
