The Junior’s Counterattack

“Yoon Seoin, you’ve completely lost your mind! How could you do… that… with your friend’s younger brother? And while drunk, no less. While your friend was asleep. Are you an animal?”
The sex from last night, which she had thought was a dream, something closer to a fantasy, had actually happened.
When she woke up with her throat burning from thirst, Jaewon was asleep with her in his arms. After reaching climax, they had both likely passed out from exhaustion. Of course, the sudden rush of alcohol must have played a part as well.
Seoin had no idea then that that one night had been planned, nor what kind of counterattack this young man would launch from now on.
Will Yoon Seoin be able to resist the young man’s temptation?
