Not even a headcanon just straight up fact that Phichit is the ultimate memelord and sends memes to Yuuri at all hours of the day. Yuuri sends them back if he’s not busy. They also send each other cute animal pics throughout the day, and will blast shitty meme music at each other from across the room.
First off, let me tell you, your fan fiction literally made my entire night and I just have it tucked away on my computer to reread because it was written SO DAMN WELL and IN CHARACTER AND OH MAN. I LOVED IT SO MUCH. YONDU'S WORRY WAS SO GOOD! UGH. But if you're still wanting prompts. How about -- Peter and Yondu get into a massive fight and they say things they don't mean, and they have to deal with the messy emotions afterward; as well as the awkward attempts to fix it.
