You and Hajime were visiting one of your friends, talking and having fun before someone suggested having a drinking game. It ended up becoming a wild night with your friend becoming drunk from it (even you were slightly tispy from it, good thing you backed out as soon as you could).

You two booked a room in a hotel before meeting your friends. But back to the present, Hajime is drunkenly snuggled up to you, hugging your arm as you guys lay in the hotel's bed. He lets out an intoxicated smile, not letting you go no matter how hard you tried. He kept clinging to you like some sort of koala.
