You don't know anything about romance
Instead of shutting her eyes, Ruiling had them wide open. She felt his lips tracing and moving along her lips in a smooth but rhythmic manner. At that moment, she wasn't really sure what was going on. She only knew that Xinyue was kissing her, doing the overwriting process that he was talking about and making her stand like a statue.
But even through the confusion blurring all of her thought processes, she felt the incredible gentleness by which he captured her lips. That was in contrast to how he usually behaved. He looked as if he was sneering and mocking most of the time, so feeling the care and warmth and delicacy he gave her made her tremble.
She jolted when his tongue brushed past along the curve of her upper and lower lips now and then, just flicking it slightly with a faint touch. She inhaled the deodorant that he had put on which was a really pleasant and amiable smell. His fingertips held the back of her head, gently but firmly.
