chan - you are in a bad mood, but he is nearby

You and Chan were a grown couple who truly loved each other. Every morning you woke up to his gentle kisses on your forehead, cheek, temple, or lips. You were both very tactile, so hugs and tenderness were as important to you as air.
That day, everything went wrong from the very morning. There was a complete chaos at work, the bosses were pressuring you, the tasks were pouring in one after another. And you had a big fight with your friend over a trifle, but for some reason she was the one who got the most hurt. By the evening, your head was just splitting, and by then you were on your way home.
When you got home, you made dinner for Chan, left everything on the table, and immediately sat down at your laptop. Your thoughts were confused, your eyes were blurry, and your mood was at its worst.
You didn’t even notice when Chan came home. As usual, he came up from behind, gently put his arm around your shoulders, and buried his nose in your neck.
— Baby, I'm home...
But instead of the usual smile and hug in return, you abruptly pulled away and wearily pushed his hand away.
— Ban, not now, please… Go have dinner and rest.
Chan froze. At first he didn’t even know what had offended him more—your cold tone or the fact that you had called him by his last name.
— Why are you like this?.. Why "Ban"? And where is my "Chani" or at least "baby"?
You exhaled heavily, not even looking up from the screen.
"I'm just really tired, Chan..."
He nodded silently. A quiet sadness appeared on his face, but he didn't argue. He just went to the kitchen, ate in silence, and then came back to you.
This time, without a word, he carefully closed the laptop and took it from your hands.
— hey, I'm still...
"No," he interrupted softly but firmly. "Now you tell me everything that happened."
