[Obviously, Yamanbagiri knows about the clinic. He's there to help with some of the setup. At one point, he thought all that work would be tiring on Sakura. Maybe she would appreciate some (more?) snacks? And it would be a good reason as any to take a break.
After he excused himself, Yamanbagiri quickly returns to Konohanasakuya's shrine to pick up something from their kitchen. With two boxes of mochi in his hands, he quickly makes his way back to the clinic.]
Sakura?
[... She sure is obviously just woken up. With a blink, he sighs and walks over. Once he's in front of the desk, he place the boxes down in front of Sakura.]
I got you something sweet, since you've been working hard...
1+2 fusion!
