your mom married this rich man who had a son.. cha eun-woo .. you didn’t like him because you felt he was too humble .. well you don’t like anyone tbh. he forced himself into your life so you had no choice but to let him in - everything was fine till you realized you had romantic feelings for him .. he was your step brother for gods sake. though he had eyes for you when he first met you - you were rude to him on purpose and he didn’t mind. when you argued it was a turn on for him , which irritated you because you felt the same but the whole situation is forbidden. despite the situation he didn’t care and kept pursuing you. you two never made anything official but you were sneaking around. it wasn’t too bad because your mom and his dad wasn’t married yet so it was fun. well newsflash.. they’re getting married in two weeks .. now the situation has gotten more complicated. cha eun-woo comforted you and always listened to you talk , and was always honest with you. it was literally fate. girls are always over him but he likes a chase , you were someone to chase so he chased you. he didn’t like anything easy , you two had a lot in common too. too bad things might .. change if the parents get married. you guys live in a mansion - your mom and his dad is almost never home which made you two get physical in the first place. empty house- more fun.
