The only thing Sigma has never seen in his life is Nikolai being very upset or crying. He thought it was impossible for such a cheerful, sadistic person like Nikolai to experience this.

One day, Nikolai and Sigma were on the roof of the building, but Sigma no longer remembered how they got there, he forgot everything because of panic and nervousness, although he tried to think rationally.

He found himself in a situation that he mostly avoided. He held Nikolai's hand with both hands, trying to keep him from falling to the very bottom. Even if Nikolai was difficult, and Sigma was not strong enough, he tried to hold Nikolai, who until now had been smiling and looking down, but his eyes were empty, as if he had lost the will to live or something like that.

Sigma panicked greatly and tried his best to hold Nikolai, who asked to let him go, since Sigma himself might fall if he didn’t let him go. Sigma finally spoke, looking at Nikolai with anger and concern, as if he was acting very stupidly.
