Example sentence: 雖然當我們在一起的時候有時候我不常常說話、而且我可能正顏厲色、我要讓妳知道我很開心。
Intended meaning: Although when we are together sometimes I don't talk very much, and also my face may be solemn, I want to let you know I am happy.
Is there a specific order? My second guess would be:
當我們在一起的時候雖然有時候我不常常說話、而且我可能正顏厲色、我要讓妳知道我很開心。
