1. Watch this only after watching something heavy/thriller. Otherwise, you'll just get bored. The story is plain. There's no development.
2. The girl is too naive it's annoying.
3. This is like-- you cut that part from a normal drama where two become couple and do smut. That's it. Just longer.
4. Recommended IF you're looking for a buffer or just want some quick romance. No intro or what not.
5. No, it's not darker than 50 shades but definitely mature content.
6. Dori Sakurada is eye-candy.
