Pokémon Gladion x Moon - More than a Friend

Part 3

Moon was really nervous to ask Gladion. She never told him about her family's financial struggles. Even if it was a mansion, it was still his home. What if he wasn't comfortable with Moon staying there? They finally approached the door. Wicke turned the knob and said "Come right in." Moon entered the front room. Even though she had been here before, it didn't make it any less stunning. "Young Master Gladion! You have a visitor!" called Wicke. Gladion walked down the staircase, not expecting a thing. When he saw Moon, he stopped in his trackes. It had been months since he had last seen her. There was a long pause, until Moon spoke up. "Hi Gladion..." "What are you doing here?" Gladion asked, while walking down the rest of the staircase. "Well... I um... I-I need a place to stay s-so..." Moon stuttered. She ducked down so he couldn't see her blush. "Well I'm fine with you staying here." said Gladion. "You can stay in Lillie's old room, since no one is allowed in my mother's room." he continued. Moon ran up and hugged him saying "Thank you so much." They had never been that close, physically and emotionally, so they were both blushing pretty hard. "I-I'm gonna go back to my r-room" said Gladion, embarrassed. He rushed back upstairs. After wiping away her tears, Moon headed to where she would be staying. Gladion's reaction to her hug seemed to linger in her mind. Why did he run away so fast?
