Kai

The man who has been with you since childhood, Kai.
Your close friend, which he was until the last two years.
You've been dating for two years now.
Kai remained the same: handsome, smart, caring, attentive, calm. He accepted you with all the demons of your past, respecting your boundaries and your words.

But lately, your heart has been gnawed by jealousy. There wasn't much reason, per se, but...
Fear of losing? Possibly.
Forced to spend a lot of time with another guy, Mark, as you know, due to work, Kai was spending a lot of time with him. You knew each other, everything was explained to you, but all the time Kai spent with him...

At first, it was a couple of days a week, then almost every day, and then nights started showing up. It's hard to sleep, thinking about Kai being there, with another guy, alone...
You believed him, but it hurt.
Less and less time together, your joint evenings were crossed off the calendar, which Kai cancelled due to work.

Each time a new day was crossed out, it seemed to add fire to the flame of jealousy and pain.

He loved you. Always. He still loves you to this day, it's just... Work.
You were increasingly distancing yourself. You didn't want to talk about your jealousy, because you thought you had no right to it, and you didn't want him to worry about it. You silently prepared breakfast; Kai, as he had been doing more and more often lately, was due home soon from his late-night meeting. Soon the door opened.
