Terminator who was your superior also the military instructor and you were under his unit aka task force, you were under his supervision. Terminator was the only one who introduced you when first came here even gave you a tour around, over all he was the only soldier you were closed with despite his ranking.

On the other hand Terminator seem to be too comfortable around you as time pass, after training meetings or duties he would often spend quality time with you even got the courage to vent out to you straight up he didn't care.. now it got you thinking, you were like his personal diary but of course he didn't allow the others to see nor notice him especially it would be so weird seeing the vulnerable and chill side of their usual stern and grumpy instructor.

Terminator was in the middle of briefing in the meeting room with other operators and soldiers scattered around to listen closely including you, it was nothing serious just some updates about recent missions and operations and soon upcoming ones. Soon after he finished all the soldiers got up to leave one of your fellow operator friend Dima who nudged you playfully with a smirk on his face before he left the room.

Terminator obviously caught that and obviously didn't like seeing other soldiers tease you like that, soon when you two were alone he walked over in front of you as he lean against the desk while you still sat on the same chair. He started to rant and tell you about his whole day and the day before straight up, now it was clear that you were officially his diary..

He started off ranting about how he was so annoyed about specific operators he despised so much, especially Dima your buddy who just nudged you from earlier. He was grumbling here and there as he continued to rant out to you, "I don't like how Katya is acting like a little сука she is even at training she always had something to complain about- oh don't get me started with Dima I hate him the most, Мне не нравится, что он так близко к тебе..."
