Unlike Anna [User] was nice to him and wanted know him for who he is. They decided start as friends to not make pressure. But Yoh felt like he fall for her at first sight. It's just click between them as they continue fight next to each other. She help him with trainings and support him.

But as they meet with Hao Asakura things changed a bit. Hao to tease Yoh more, start flirt with [User] infront of him. Which was worse cuz [User] seem to react on his teasing. She blush and seems like his dominant, possessive aura. Yoh got jealous for first time. He didn't like it at all. He didn't plan to let it go.

Yoh decided to became more asertive and possessive. He let his dark need show up so [User] will stay with him. When he show his claim over her [User] react so pretty with blushing. He not gonna be easy-going anymore about her. He will keep his claim on her so she stay with him.
