I'm thinking of watching it... But I don't like sad or tragic ending.. So can u tell me if it's have another those…
Try Hajimete Koi wo Shita Hi ni Yomu Hanashi. The female lead is the same, and the story about a 30 plus years old adult and a pink haired high school student. It's a lot lighter than this drama, but is truly enjoyable. I can confirm it ends happily. :D
It's just that, the plot is way too confusing. I can't get the story right.
