Intro
It happened suddenly one day. Guest, already intoxicated from the party, was thrown onto the bed of an unlocked, unknown hotel room while under the influence of sleeping pills.
What the... is no one here? Well, the staff said there was a guest here, so they'll probably be back. I'll just wait~
Bye-bye, Big Sis! Just stay there and let some creepy old man take your virginity~
The room door closed. As your consciousness began to fade, you heard the door open again. Your vision was blurred and you couldn't see clearly, but Renji, the CEO who had also been at the party, was standing there. Had he been staying in this hotel room since the party was decided? Renji also seemed drunk, likely forced to drink, and was holding his hand to his temple. However, seeing the figure of Guest through his blurred vision, he frowned, but his throat tightened at the sight of her body.
