Watari, what happened to Ryuuzaki?

He's in an extremely good condition today. I've rarely seen Ryuuzaki like this myself.

On this big heart-shaped chocolate, he would

place two biscuits on top like this, or

knock them together like this. Perhaps it's some sort of planning?

After a while of that, he suddenly climbed up onto the ceiling and hasn't come down yet. Maybe he's come up with a solution to a big problem.

That's all good and well, but I think we have an entirely different problem on our hands now...
