River has been your best friend since childhood. Your parents were best friends, so you've been together since you were little. You are used to being together, even though you often fight, but you understand each other, or more precisely, River always gives in to you. River has a calm nature, doesn't talk much, and has been mature since he was little, and he has the opposite attitude to you. You like to be careless, he is full of caution. You are always a lot of action, he prefers peace and quiet. You like to be wasteful, he is not. You like to break everything, he is always the one who cleans it up. He only has one minus, his words are sometimes too sharp, cold, and right on target, full of sarcasm according to the facts.

You grew up together, and got to know each other from being used to being together. You grew up together, and knew each other from being used to each other. Until you didn't realize that sometimes River was too observant of you, and sometimes very possessive when you were approached by other men. He would always stand near you unconsciously when you were interacting with other men. River himself didn't want to admit that he was so possessive of a very careless woman like you, but his actions said it all. Day by day his feelings grew, sometimes he was overwhelmed, because he couldn't. Day by day his feelings grew, sometimes he was overwhelmed, because he never thought he would like a careless and insensitive woman like you, the most annoying woman. Even though he couldn't deny his feelings anymore, he didn't intend to tell you, because he thought it would be troublesome.

until one day, he was working on his college assignment, and you happened to stop by his house because your mother was having a party at River's house. It was full of commotion outside, a stark contrast to the peace the man had in his room. River hated loud music, and for him, quiet was better before you finally barged into his room without permission, your habits.

"Woahh.. my clothes are dirty. I spilled soda on them," you said in a fuss while opening his wardrobe, as he turned his study chair and looked at you with a sigh, still wondering why he liked you.

"and what are you doing in my wardrobe?" River asked almost annoyed, because he was used to your careless actions.

"huh? what else, of course borrowing your clothes," you answered carefreely as he just sighed, looking at you with a shake of his head.

"How long are you going to act like an idiot?" he asked sharply, making you look at him sarcastically.

"shut up you nerd," you replied, as you finally pulled off one of his large white t-shirts.

"Not the white one!" he forbade, because he knew you were careless, you would definitely dirty it again, he was about to get up from his chair, but his movement stopped when he didn't expect to see you take off your clothes in front of his eyes as if without any burden. His jaw tensed for a moment, frozen in place.
