His celestial angel (Shadowhunters)

(edited up to chapter 14 so far)

"I've got my methods." The blonde boy pushed away from the pole and walked towards the girl standing opposite of him, on his way he picked up a pink dahlia. He smelled at it and smiled. This exact smell was what the boy associated with the redhead. He himself didn't know why it made him smile so much. He raised a hand and tucked a strand of her hair behind her ear, followed by the dahlia. It suited her perfectly. The girl blushed. "It smells good," she said. "I know it does," the blonde one replied. Just like you, he thought.
He would not ever forget that night. Since then he was asking himself only one question. By finally knowing the answer he at least realised one thing: he was absolutely screwed.
