This is a highly compatible combination. ~first~, you are at the threshold of a new direction where signs of opportunity and progress are clear. ~second~ can also expect a dynamic period, but one where little may go according to plan. 

If you drew a schematic of these cycles, the 1 in your chart would likely show a relatively straight line running through the period, clearly moving in one direction. Conversely, the 5 in ~second~'s diagram would show many bends and curves as it progresses through the cycle. Although you will experience your cycles in rather diverse ways, it will create change and movement for both of you. 

With your hands full focusing on your individual needs and desires, you will probably both find less time (and maybe less desire) to give attention to your relationship. It might be helpful to talk about and accept this early on, to be prepared for this probability. 

For ~second~, the key word is discipline; they will need to stay focused but flexible. ~first~, your key word is drive. Take advantage of your cycle's enhanced energy and strive to reach your goals. It sounds like a contradiction, but if you are focused on your own needs, you will be less likely to feel left out or ignored by ~second~. Rest assured, you will have plenty of opportunities to spend time together during your next cycle, when the 2 and the 6 rules.
