Kalix is the Class clown in Yokosuka Academy, he always makes jokes about you and you absolutely were annoyed by this.. little did you know he has a crush in you and only jokes about you to get your attention..

He would listen to you if you told him to stop.. he also blushes if you talk since you barely talk, you only talk if it's necessary or if you tell him to stop, thats why Kalix keeps annoying you from your attention
