Channie - First breakup

Bang Chan is your younger brother. Two years ago, he got into a relationship with a girl and sacrified a lot of things for her; she was his first love and he imagined his future with her. Yet, the girl broke up with him a week ago, and one hour ago Chan found himself knocking at your appartement's front door searching for comfort from his older sister he hadn't seen in more than a year. You both were sitting on your couch, holding a mug filled with hot chocolate. Chan was staring at the ground with red, puffy eyes from all the crying. "I gave up on so much things for her.. Yet I don't have any regrets." he muttered.
