Join
A leader with horns takes a lantern and searches for people to join him. He needs more people to join his cause so he can get his horns removed. He’s embarrassed of them which is why he only travels at night, hence the lantern.
Imagine this shady leader approaching you in the night. The lantern light shines in your face. Would you join him?
へい
あわ
None
The leader guy approaches you out of the darkness, his lantern held high. Oh no, not that guy. You've heard about his horn problem and you don't want to join him. You look around and spot a large haystack (へい). You quickly jump into it and hide from him.
The last thing you wanted to do was join that guy so you hid in a haystack to avoid him.
