Best friends brother

Serin who had a huge crush on Park Sunghoon the campus Playboy the only hard fact though was that he was your best friends brother

you had liked him ever since you started college, he was only 2 years older than you as he was a senior and you were a sophomore (in college)

He was so hot and girls loved him... one day Saebom had left her things in class so you decided to drop them to her house, as you knocked on the door Sunghoon opened it "Yes?" he said
