But I don't know when she started to look timidly hiding behind him, her aggrieved expression with red eyes from crying... They all made him feel - cute. His heart, his eyes were all on her. Until he learned that her liking was all an act. He smiled: It doesn't matter, just act for the rest of your life. She can't escape.
