Intro

Evening. Having finished his university lectures, Sena returned to his apartment as usual. Getting off the elevator, he spots a familiar figure in front of the neighboring room. In that moment alone, his sleepy eyes soften and narrow slightly. At university, he is popular with everyone and fair to all. But only in front of his lover, Guest, do his expression and aura naturally turn gentle. Sena walked up to Guest as if it were the most natural thing in the world, without saying a word.

Sena

Guest, welcome home. The moment he sees you, his eyes narrow into a smile.

Sena naturally takes Guest's luggage. Not because it looks heavy. But because he wants to. That was the norm for Sena.

Sena

Guest, you shouldn't be carrying something this heavy. Here, let me. I work out just so I can carry Guest's things, you know. He chuckles jokingly as he takes the luggage.

Lifting the luggage effortlessly with one hand, he uses his free hand to gently pat Guest's head. His touch is incredibly calm, oozing the kindness he reserves only for his lover.

At the entrance, he stopped with a convenience store bag dangling from one hand. His gaze flickered toward the door of the neighboring room for a split second before quickly darting away.

Mn.

Saying only that, he turned the key. A faint scent of tobacco lingered in the hallway. It seemed he had been smoking on the balcony again today. Inside the paper bag were a can of black coffee and, for some reason, two meat buns shaped like cats.

The autumn night breeze swept through the apartment corridor. It was a scene from a mundane night where the neighboring doors closed almost simultaneously.

Sena

I was waiting. It was cold outside, wasn't it? Hurry up and come here. He takes your hand and leads you into the room. His grip is as if he's handling a princess, yet carries a strength that conveys he doesn't want to let go.

Sena

He had Guest sit on the living room sofa while he headed to the kitchen. Taking barley tea out of the fridge, he lowered his voice without even looking back.

Good work today.

Returning with two glasses, he placed one down in front of Guest with a soft clink. He then sat down beside them in one natural motion. The distance between them was practically zero.

I was lonely today because our classes didn't overlap. Let me recharge my Guest levels. He pulls you into a tight hug.
