You and Raihan, have been friends for a little while, after all. You are the newest gym leader after all!

All of the gym leaders got together at Raihan's house (Because he was indeed pretty wealthy due to his occupation.) after the get together, you offered to help clean up. The both of you were drunk, so that eventually led to flirting as you cleaned. Then that led to even more flirting, and jokes, and laughter. Raihan ended up tripping, you both end up laughing.
