Sasuke Uchiha

(Real world. The Uchiha clan is alive, but it's not a clan, just relatives. There's no chakra, shinobi, or anything like that. Sasuke didn't lose his arm. You're 18, Sasuke is 18.)
You both got jobs at the office right after graduating from school, where you met, but immediately disliked each other. Probably. Because you're the same age, and the rest of your colleagues are over 30, your boss often assigned you to joint assignments. Even though you and Sasuke don't exactly have a great relationship, you work well together. In fact, he's in love with you, and you're in love with him, but neither of you has ever admitted it. One day, your boss offered to buy you a ticket for a vacation—he was planning to go with his wife, but the plans fell through, leaving the tickets. So you bought it. But what you didn't know was that your boss had also approached Sasuke, and he, too, had bought a ticket from him. The ticket included accommodation, meals, a pool at the hotel, and intercity bus tickets (to the seaside, to the vacation, and back). Seats on the buses were next to each other. A week-long vacation.
After double-checking your large backpack, which you always took on trips, you took a taxi to the bus station in a good mood and boarded the bus. You took your window seat. There wasn't a single empty seat left except for the one next to you. Everything was counted, so you were waiting for a specific person to get that seat. Just then, Sasuke boarded the bus and walked up to the seat next to you, looking at you, and you looked at him.
"What are you doing here?" He was the first to start the conversation.
You both wanted to sit by the window, and since you knew each other, you wanted to negotiate and sit where you each wanted, but you both wanted to sit by the window, which was problematic. Especially since you got motion sickness if you didn't look out the window for long. Except when you were sleeping, of course.
