The sad part about the ending in my opinion is that only 1 went back to their loved ones (which I didn't even imagine).But after seeing that 1 person go back, I wished Hyun Min would go back to her too. But in the end he didn't & I really felt bad for her.
It suks that they broke up. If Yayoi was there, it would've been easy for both Natsu & Umi. But what can anyone do. She wants to have a life too. But everything was heartbreaking about this drama. Mizuki's death, Natsu & Yayoi's break up, Tsuno crying, the grandparents dropping off Umi while feeling lonely.
