"""Sunbae…! I want you now!"" This is it. After having a hopeless crush on him for three years...it's all finally over. Or so I thought. ""I’ve changed my mind. Go out with me."" Three years of rejection, and all it took was one night in bed? Unbelievable. Furious, I walked away…and didn’t look back. But now, that arrogant sunbae has reappeared, asking for my help. ""No need for money. Why don't you convince me with your body instead?"" ""Are you sure you won’t regret it?"" ""Are you any better in bed now?"" What started as a challenge—payback for the man who once crushed my pride—quickly turns into something far more dangerous. This time, who will be the one in control? Let’s find out."
