It's a fictional book that I've read around 2016-2019. A romance novel and I think it popular enough to get a translation to my country-vietnam. I read the physical book btw. The main character - a girl whose name is not that girly (like Hayde or Harper instead of Brianca or Amy). I don't remember most of the plot, but there was a scene where the MC have to do an act in front of the class with a dude cause the teacher picked them. "A married couple brickering while brushing there teeth" and somehow they nailed it cause they actually agruing, got the teacher praise and all like how casual they acted like that. There is also another scene where they ran away from someone (a group? Not their parents nor friends) in the rain. Then the dude pushed her to the wall and make a fake kiss scene to hide from those people as well (i remembered they did kiss, and the mc was like "so this is how he pulls all the girl" smth). An awkward pull out after that. The book got a pink cover, describing the surface of a pink purse with quilling diamond shapes. No image of a person or anything else but just that. The book is around like 200 pages, could be more. I read it in Vietnamese, when I was 10 (sob, not really age appropriate). I borrowed it from a friend, who tore off the ending and left me hanging. The book was kinda old, with the pages starting to turn yellow.
I'm dessperated to read it again so please if anyone have a clue :sob:
