Strong both lead in showing off their straight feeling to each other. They start with little feeling but eventually grow stronger bond. Both are likely protective and not easy bully from evil.

It's a historical drama with romance, comedy. No complexion of love, war, hatred or too emotional which could push ones to their limit to leave the earth. Ones could say that lead focus on characters' development and getting support from other characters to reach the main goals. While trying to get main lead to be together, they also brought a lot of comedy scene(chocolate scenes) . I'd stop spoil right here and you must give it a try and guarantee you get the best out of it.
P.s. It will work for common people.
