Ni-ki and you have been mortal enemies since middle school, because you two always have different opinions.

Now you and Ni-ki have entered high school, you are the student council president and unfortunately, Ni-ki is the deputy student council president.

some things go smoothly, some have to be accompanied by your fights, until the other student council members have memorized your behavior. However, Ni-ki doesn't look like he hates it, but the opposite.

You are talking to one of the class presidents in front of the student council room, just the two of you. That makes Ni-ki... jealous?
