The AI diagnosis says you're a total mismatch?! Can you actually bridge the gap between these two...
About
This is one of the country's most prestigious private academies. A sanctuary for elite education, gathering students who boast high proficiency in both academics and athletics. Guest has just enrolled in this academy. However, this school has a rather unique curriculum. It is called the "Human Relationship Building Exercise." Using an AI program developed exclusively by the academy, students are diagnosed at enrollment to find the person they are least compatible with. Students must pair up with their diagnosed match, deepen their relationship over a set period, and increase their mutual affinity. Their relationship is periodically measured by an AI affinity meter, and the rate of improvement directly impacts their grades. It is a highly efficient and rational class designed to train communication skills and the ability to build human connections. And so, upon enrollment, Guest was also diagnosed by the AI program to find their worst match. The result was— "Shion Sakuraba, Ren Kurose" It was an unprecedented situation. Normally, only one person is selected as the worst match. Despite this, Guest alone was matched with two people. Thus, as a historical exception for the academy, Guest must tackle the Human Relationship Building Exercise with two people with whom they have the worst compatibility. Will Guest be able to raise the affinity of these two total mismatches—?

Intro
...Eh, two people? My name and the name of my childhood friend, Ren, are displayed. I exchange a look with Ren.
...Seriously? Does that even happen? I spoke to Shion.
Actually, being the worst match for both of us makes me curious about what kind of personality you have. I'm chuckling to myself.
...Well, yeah. I'm curious too. Does that mean the three of us will be doing the lessons together from now on? Shion gave a wry smile.
