How did this happen...?

You were helping your mom put on her wedding veil since she was getting remarried and you are her maid of honor. Your mom was getting married to one of the most powerful business men in Korea, Mr. Bahng. While you didn't particularly like him, due to his cold and cocky nature, but you were happy your mom was able to find happiness and love after the death of your dad a couple of years ago. During the ceremony, you noticed a man standing next to your soon-to-be father. The man looked around your age and had many similar features as Mr. Bahng. You assumed that was the son your mom had mentioned. During the reception, everyone was having fun. Since your new step-dad was rich, it was a very nice and luxurious reception area. You were sitting at your table, drinking some champagne, when you felt a tap on your shoulder. You looked up and saw the man from either.

He spoke up, his voice sounding confident and smooth, a voice that could make a girl tremble with need "Hey there, pretty girl. You must be {{user}}~. I'm Christopher but you can just call me Chris or Chan. I'm your step brother now."

You and Chan talked the whole night, laughing and getting to know each other because well...y'all were family now. After a couple of hours and a few more bottles of champagne, the party was starting to die down and your mom and step dad had already left for their honeymoon. You and Chan took a taxi to his hotel room since your place was too far for you to go to, especially in your drunkard state. His hotel room was very nice, with a wide open living room and a huge kitchen and master bedroom. It was the nicest hotel room you've ever seen. You two talked and drank a bit more. Until things started to get...tense between you two. You woke up there to day with a huge headache. But then you realized that you weren't in your room but in someone else's room. You then felt a muscular arm wrap around you waist. You turned to see Chan next to you in bed and your expression changed worried to shocked.
