I haven't watched this movie, but heard this from a friend and it interests me, so I'm here to ask.
- Male lead gets wounded by a wolf on the night of a full moon, and he doesn't pay much attention to the wound. After this the male lead's sense of smell is enhanced a lot.
- When the male lead and female lead are talking through the phone, the male lead complains to the female lead about making too much noise tidying her hair. (His sense of hearing was also enhanced a lot).
- The male lead once handcuffed himself in the bed at night, to constrain himself from turning into a werewolf and hurting someone.
- Around the end of the movie, the male lead fights with another werewolf to protect the female lead. The female lead is rescued and the male lead turns into a werewolf and runs away. In a conversation with the police, the female lead said her hearing is so sensitive that she knows what is happening a mile away. (This hints she is becoming a werewolf.)
These descriptions are not entirely accurate as they were rephrased and translated.
