Imagine someone saying hide your powers it's not good enough for me and I'm scared of it. You don't need to protect me with that powers of yours. I'll just have to get stronger and I'll protect myself. Yayul felt the same, if he could channel his power in the right direction then our FML doesn't need to keep on telling yayul to hide his power. In fact he can use it without hiding it

I really wanna know why did Yayul felt so conflicted with Yeon's answer to him. He even went and became the old man's disciple! Can someone please spoil me about it?
