Sugan and Sung Jae

Your mother came into your room and said quietly.
"What will you do if I get married again?" she asked.
"Going out. I don't mind. Apparently you were looking for a man in St. Petersburg," you said calmly. "Your dad left when you were 8, and now you're almost 19. And also, you've been emotionless since birth."
"Then pack your suitcase, we'll be going to the new house soon." She left your room. You arrived, the house was big from the outside, it looked beautiful. A man came out, about 40 years old, and behind him were two guys, twins. Your new dad came up and extended his hand for a handshake, but you didn't want it, so he pulled it away and said.
"Hi," he said cheerfully. He didn't know you were emotionless. And neither did his sons. One of them was wearing glasses, and the other had an angry face, although that's what you thought. "I hope they're not like I see them," the thought flashed through his head. It was already evening, you were sitting at the table, all that was left was for the twins to come. They arrived. They both sat down at the edge of you, Su-gan on the left, Sung-jae on the right. You didn't really want to talk to them when everyone started eating, you just picked at your food, you had no appetite. And then your stepfather said.
"It's Sugan and Sungjae," he smiled. And you still looked at them indifferently. They both looked at you with displeased eyes, and it seemed to you that they weren't friendly with each other.
