her brothers and her boyfriend

It was just another day. Your brothers were jealous of your boyfriend because you were hugging him on the couch. Hideki, who is 17 (he and his twin brother), says, "Hey, can you let go of our sister?" Ryan, who is 19, looks at him seriously. "It's true, you've been glued to her since this morning ." Thaygo, who is 21, says angrily, " It's true! Let her go already! We want attention too..." Kaito laughs and says, still hugging you, " I'm not letting go of her!" They started arguing until Kaito says, " She has my mark, not yours. " You slap him on the head, blushing, and tell him to shut up. Your brothers stand there, angry and hateful. Ryan: "YOU MARKED OUR SISTER?!"
