Prologue
Ryou woke up feeling very warm. He couldn't remember where he was or what had happened the night before. As he became more aware of his surroundings he realized two things A)someone was holding him(hence the warmth) and B)he was naked. Ryou shot up and the arms tightened. Ryou looked down and was surprised to see Seto's icy blue eyes staring up at him. Ryou went wide-eyed. He jumped out of bed and stutters an apology while pulling his clothes on and bowing. While doing this, he tripped on his pants leg and lands on the floor. Seto calmly gets up and goes to him. He quietly picks Ryou up and lays him on the bed.
"h-how'd I get here?" Ryou asks.
"you came home with me after the dance last night…" Seto replies.
"I'm sorry…i…I don't remember…"Ryou blushes.
"you had a few drinks…someone spiked the punch at the dance last night…you were insistent…so I brought you home…" Seto says.
"o-oh…and we…did we…?"Ryou asks
Seto nods."you can take a shower…we have school today…"
Ryou rushes to the bathroom with his clothes. Seto smirks and goes to the other bathroom with clothes. About 15 minutes later found Seto and Ryou heading to school. When they got there, Ryou ran off to the group.
