Aggression
Construction in the winter leads to aggression. Just think about it. It's cold, it's unpleasant, and you don't want to be there. So, you start to develop an aggression towards other people working with you on this winter project.
Imagine yourself walking through the winter construction site, taking out your aggression on anyone you see. You hate this winter construction!
こう
せ
None
You're taking your aggression out on everyone. Then, the sexy construction worker from WaniKani Level 1, こういち, walks by without a shirt on. You take out all your aggression on him.
"Aggression" is going to depend on you, so you should imagine a scene where you take your aggression out on こういち, whatever that entails. Hint: When you see the radical construction (工) in a kanji, it will often take the こう reading.
