[Since he'd come to work at the Cherry Blossom cafe to help Sakura over the past few weeks, today he's holding down the fort there while she's out, until the presents that float around outside clue him in to the importance of this particular date. So when she gets back, she'll find that he put together something to stand in for a birthday cake -- a hasty effort on the short notice and his limited abilities in this particular sort of thing, but the cherry blossom-shaped pastry and the candle is something, along with a few of the flying presents he managed to catch.]
Sakura-san?
I hope you don't mind I did something for this, but... Happy birthday.
