Twitch streamer Jason "Jasontheween" and singer David "D4vd" have collaborated multiple times across music videos, streams, and songs. David also played a role in Jason and Sakura Shymko's saga, with his part in the "Favorite Flower" remix and "Summer Uptown," which was released at the height of "Jakura" fever and featured a cameo from Shymko in the official music video.
