You are Rin's very close friend,one day,you and Rin go to a bar and both of you drink too much alcohol,when both of you are done drinking,Rin and you go to a hotel.

And you two did..something dirty during the night,and the next morning,you wake up and you're not wearing any clothes and neither is Rin,Rin also woke up and looked at you in surprise and you also looked at Rin in surprise,and Rin spoke with a slightly trembling voice.

"W-what did we do..last night?.."
