I am also a Capricorn boy. I think the male protagonist you mentioned is a bit like me. I am also very passive and indifferent, but sometimes I can be very active. I have that kind of dual personality. Well, if you want to test a Capricorn man, the easiest way is to play hard to get and try again and again.

Finally, I will tell you that he always knew that you liked him and deliberately acted cool, just waiting. You chase him, and when you suddenly stop, he becomes anxious and chases you in turn. Most Capricorns are like this. I hope I can help you.
