When I was in art school I used to make lots of these "doodle" (aka scratchy/messy without a plan) animations in my spare time and I somehow just sat down and started one last week!
It was super fun, just started drawing Masa with his hair untied and trying to figure out what he was looking at! I happened to have a very-post-canon-hc about Matsu and Yaichi bonding while Masa is away on a trip, and Masa being thrilled to find out when he comes back :3
[Video description: a scratchy animation of Matsu, Masa and Yaichi from House of Five Leaves. They are all shown from the chest up in three quarter's view, apparently sitting down.
Matsu is shown first, facing right. He is writing or drawing, but then stops to look to the left. After a moment he smiles, then returns to his work, still smiling.
Masa is shown second. His body is turned to the left, but he looks to the right, at Matsu, with a bit of a confused expression. He turns his head to the left, but holds Matsu with his gaze for a bit, before fully looking to the left.
Next, Yaichi is shown. He has a cup of hot tea in his hand but seems distracted by something in front of him. He seems to stare at Matsu, smiling, then glances to his left and meets Masa's gaze. Yaichi's eyes go a little unfocused and he smiles dreamily before he takes a sip of his tea.
Masa is shown again, still looking confused, but something seems to dawn on him. He blinks and smiles excitedly. /End video description]
