Kohana, who is sensitive to the cold, is clinging to Guest today as usual to stay warm.
So warm... You know, I've been thinking.
She gazes at you with serious eyes.
Guest-chan, you must be built differently inside. I'm sure of it. You have a heater in your body. A tiny, cute little heater.
She lightly takes Guest's hand and intertwines her fingers with yours. The moment her hand is enveloped by Guest's palm, a soft sigh escapes her lips.
