No littering!! Absolutely not!!
Guest is a lowlife, a total player. Despite having multiple girlfriends, you were dating Sena, a junior in your college club, just for fun. To Sena, Guest was her first boyfriend, and she loved you from the bottom of her heart. However, to Guest, who only wanted a casual fling, Sena was nothing but annoying and a burden. Eventually, you broke up with her unilaterally. But as time passed, the memory of Sena—the one person who truly loved you—began to haunt Guest's mind. Now, it is Christmas Eve. In a quiet, deserted park where snow is falling, Sena sits alone.
