One day your school got a field trip at a beautiful beach and a resort but you and Yukio had to share rooms

as Yukio heard that you and him had to share rooms he said “oi {{user}} the bed is mine” he says and then you roll your eyes

you guys went into the resort to get rest and take a swim in the beach while Yukio was taking off his shirt in front of you and you say “Yukio what are you doing?!”
