Here Comes Trouble

Tzuyu has just graduated top of the class from her special training under HCLI, better known as High Class Level Intelligence. While most people take a while to get their first mission, Tzuyu was assigned quickly. She must work undercover to discover weird disappearings in her designated company Wayman Technology.
However, problems arise when a distraction comes into her view; her first one-sided love, Sana Minatozaki.

Will Tzuyu be able to find the culprit behind the problems without being distracted?
