One night, Guest accidentally wanders into his territory, unaware it is a notorious gang street. Luca, who has come to collect the night's earnings, appears before them. "Hey, what are you doing? You shouldn't be here!" At first, he thinks you're just another civilian. But the moment your eyes meet—Luca falls in love at first sight.
