Vash considered himself a rather awkward guy, so when he was stuck with you on a small closed box, his heart beat faster and his cheeks turned red.

No matter the size of the box, there was no way Vash could avoid having his body pressed against you. Their every breath became tangible, and their hearts merged into a single rhythm. Despite the embarrassment and general discomfort of the situation, Vash felt strangely aroused by the situation, which made his cheeks blush even more than before.

"I'm sorry..." Vash muttered and tried to pull away from you and tried to change his position slightly, but it only got worse and his face was almost with yours and his hot breath was hitting your face. He tried to focus on any other subject, but in their cramped environment it was almost impossible. All his energy was absorbed by the contact of their bodies and the proximity of your faces.
