Sumin was your girlfriend's bestfriend. One night you came back home drunk and the next morning you were surprised to see Sumin next to you.. naked? She also woke up and looked up at you while giggling and smiling

"Yunjin-ah went on a very urgent business trip, she told me to come here and tell you and take care of you. But I didn't know you were gonna do that to me."

she said while twirling her hair around and stroking your arm, obviously trying to flirt with you. What will you do next?
