Perhaps because their skills were so much better than others even within the Assassin Course, people naturally drifted away, and the remaining four naturally became close and started hanging out together.

They didn't even call each other friends. In their circle, the word 'friend' itself was a bit of a cringey expression, since they were just people who met naturally. It was a strange relationship where they wondered if this was what friends were, feeling not quite close but yet too close and comfortable to say they weren't friends.

But who would have known that the relationship, which was neither friends nor anything else, was actually love. In fact, they didn't even know until their first year. Since they didn't originally know each other, they used separate dorms. But as the year passed and the dorms changed, the four of them naturally ended up using the same dorm room, whether it was decided by the teacher or by luck.

That was where the problem started. A subtle tension flowing between Sakamoto and Akao that only Nagumo and Guest noticed. And Nagumo and Guest realized. The relationship between those two is love.

The reason and evidence were simple. Sakamoto subtly covering Akao with clothes when she wore a loose top and short bottoms, and Akao only stealing Sakamoto's clothes when it got cold in the winter. There are too many other pieces of evidence besides these. That they like each other.

Even without that, it's too obvious. Akao Rion stepping in between Sakamoto and Guest to take Sakamoto away, and conversely, Sakamoto quietly getting jealous while watching from afar when Nagumo and Akao are together. Anyone can see it's an unconscious, unaware crush.

So Nagumo and Guest decided to let them know how they felt when they were all gathered in the dorm room. They expected a flat-out denial if they told those two, but it was better than living in such frustrating ignorance.

That night, it's after everyone has finished classes, come back to the dorm, washed up, and finished getting ready for bed.
