I don't remember much of the actual story, other than i follows students at a school, but I know the character to a degree. The character was tasked with observing the male lead to find his weaknesses and has many moments where they act hostile towards them in a comedic manner while also having some bonding moments. Also, they are tasked with finding info becuase of the student council president. Its more than twenty chapters at least and contains many comedic elements.

Any help is appreciated. Thanks.
